Ivan Akimovich Akimov (Russian: Иван Акимович Акимов) was a Russian painter celebrated for his contributions to the Classical and Neoclassical styles of art. Born into a family of a typographer for the Governing Senate, Akimov's journey into the arts began early when, after his father's death, he penned a heartfelt letter to the Imperial Academy of Arts. This letter secured his admission, marking the start of his lifelong association with the Academy, where he evolved from a student to its director.
Akimov's education at the Academy was marked by numerous awards, including gold medals for his artworks, showcasing his burgeoning talent in painting. His artistic journey took him to Italy on a fellowship, where, despite initial challenges, he found mentorship under Pompeo Battoni and was inspired by the Venetian masters. This period was instrumental in shaping his skills and artistic outlook.
Throughout his career, Akimov was revered not just for his artistic output but also for his contributions to art education and historiography in Russia. He played a pivotal role at the St. Petersburg Academy of Arts, ultimately serving as its director. Akimov's legacy extends beyond his paintings, through his influence on future generations of artists and his foundational work in Russian art historiography. Among his notable works are "Prometheus Making a Statue at the Command of Minerva" and "The Baptism of Princess Olga in Constantinople", which reflect his classical influences and historical interests.

Eleazar Albin was a British naturalist and author of illustrated books on birds and insects.
Albin wrote and illustrated a number of books, including A Natural History of English Insects (1720), A Natural History of Birds (1731-38), and A Natural History of Spiders and Other Curious Insects (1736). His work was based on careful observation and artistic talent. Eleazar Albin has been called one of the "great illustrators of entomological books of the 18th century".
Some of the illustrations in these books are by Albin's daughter Elisabeth. Eleazar Albin himself proudly wrote of his drawings that they were all painted from life, with all the accuracy of a sketch, unlike the sketches of other scientists, who did them either from memory or from stories.
Aristotle (Greek: Ἀριστοτέλης) was an Ancient Greek philosopher and polymath, renowned for his profound impact on Western philosophy and science. Born in Stagira, Chalcidice, Aristotle's intellectual ventures spanned a multitude of subjects, including but not limited to physics, metaphysics, poetry, theater, music, logic, rhetoric, politics, government, ethics, biology, and zoology.
Educated in Plato's Academy in Athens, Aristotle distinguished himself as a scholar of vast knowledge and influence. His foundational works laid the groundwork for the development of modern science, while his teachings on logic and the syllogistic method continue to resonate in the realm of philosophy. As the tutor of Alexander the Great and the founder of the Lyceum in Athens, Aristotle's legacy extends beyond his prolific writings, with his teachings shaping medieval scholarship and influencing both Judeo-Islamic and Christian theologies.
Among Aristotle's notable works, his treatises such as "Nicomachean Ethics," "Politics," "Metaphysics," and "Poetics" have been studied for centuries. His concept of the "Golden Mean," advocating for a balanced and moderate approach to life, remains a cornerstone of ethical philosophy. His ideas on the "Prime Mover" and empirical evidence as a basis for understanding the world laid the foundation for scientific inquiry. Although only about a third of his original output has survived, Aristotle's contributions continue to be a subject of academic study and admiration.
For collectors and experts in art and antiques, the philosophical and scientific principles of Aristotle's works are not just historical artifacts but living ideas that continue to shape our understanding of the world and our place within it. His insights into the "good life" and the pursuit of happiness are as relevant today as they were in ancient Greece.

Caelius Aurelianus was a Greco-Roman physician and theorist of medicine, representative of the Methodist school, and author of treatises on medicine.
He is best known for his translation from Greek into Latin of Soranus of Ephesus' lost treatise On Acute and Chronic Diseases. The bilingual and intercultural nature of the text makes it an invaluable contribution to the study of Greco-Roman medicine.
Cornelius Gerardi Aurelius, also called Goudanus, was a Dutch humanist scholar, writer, and historian.
Aurelius was a permanent canon (monk) of the Augustinian monastic order and is one of the first humanists of the Netherlands in the 16th century. He wrote poetry, historiography, hagiography, political and theological works. Aurelius also corresponded with many of the famous men of his day, especially Erasmus.
Henry Walter Bates was a British naturalist, biologist and traveler.
As a young man, Henry worked in a factory and attended the local mechanical institute, where he excelled in Greek, Latin, French, drawing and composition, later learning German and Portuguese. He also practiced classical music and was an avid entomologist.
In 1844, Bates met entomologist Alfred Russel Wallace, who a few years later invited him to go to the tropical jungle on a scientific expedition. In May 1848, they arrived in Para, Brazil, near the mouth of the Amazon River. Wallace returned to England four years later, but Bates remained there for a total of 11 years, exploring the entire Amazon Valley, where he collected some 14,712 species, mostly insects, of which 8,000 were previously unknown.
On his return to England in 1859, Bates began working on his vast collections and preparing a famous paper published in 1862 entitled Contributions to an Insect Fauna of the Amazon Valley. In 1864 Bates was appointed assistant secretary of the Royal Geographical Society (London), a position he held until his death. He wrote The Naturalist on the Amazon River (1863), as well as many works on entomology.
Bates's work in demonstrating the action of natural selection in animal mimicry (imitation of other living organisms or inanimate objects) provided strong support for Charles Darwin's theory of evolution. Much of Bates's insect collections are in the British Museum.
Pierre Bersuire, also known as Petrus Berchorius, was a French medieval writer, Benedictine monk, translator, and encyclopedist.
He was the leading French scholar of his time and friend of Petrarch, author of encyclopedic works on morality, and the first French translator of Titus Livy's History from the Foundation of the City. Very interesting for researchers is Pierre Bersuir's text Ovidius Moralisatus - written in Avignon in 1340 and spreading rapidly, it is a systematic allegorical analysis of the Metamorphoses, aimed at the current situation in church and society.
Bersuire was also an eloquent preacher and author of voluminous sermons.
Matthias Bernegger (latin: Bernegerus or Matthew) was an Austrian and French scientist, astronomer, mathematician, linguist and translator.
He was educated in Strasbourg, where he developed a special interest in astronomy and mathematics. Bernegger corresponded with the famous scientists Johannes Kepler and Wilhelm Schickard. From 1607, Bernegger taught at the Strasbourg Gymnasium, and in 1616 he was appointed professor at the Academy.
Bernegger is known for his translations of Justinian and Tacitus, and in 1612 translated into Latin Galileo's 1606 work on the proportional compass, adding considerably to it. These additional detailed annotations by Bernegger made Galileo's compass much easier to use, making it the first mechanical calculating device that could be applied to a wide variety of complex problems. In 1619 Bernegger prepared a three-volume manual of mathematics, and in 1635 he translated Galileo's Dialogue on the Two Mass Systems of the World.
Johann Hartmann Beyer was a German physician, mathematician and statesman.
He earned a master's degree in liberal arts at the University of Strasbourg, and then graduated from the University of Tübingen with a doctorate in medicine. In 1588 Beyer returned to his native Frankfurt and began working as a physician; a year later he was appointed Physicus ordinarius - his duties included overseeing the city's health care and pharmacy system.
In 1614 Beyer took up the position of senior burgomaster of Frankfurt, but during the Fetmilch Rebellion he became involved in conflict, was forced to resign and returned to science.
He had the richest library of scientific books, numbering about 2500 volumes, wrote scientific works on astronomy and mathematics, engaged in medical activity, having invented the famous Frankfurt pills. Beyer carried on a lively correspondence with scientists, including mathematician Johannes Kepler, dealing with decimal fractions. Beyer bequeathed his rich inheritance to the city and to charity.
Jan Bleuland was a Dutch physician, medical scientist, educator and writer.
Bleuland was an intellectually advanced man, a sought-after physician, and a rich lover of the arts. Jan Bleuland taught anatomy, physiology and obstetrics for 31 years and was professor and rector of Utrecht University. His talents as a physician and medical researcher were recognized not only by his patients and the scientific community, but also by the highest authorities.
During his lifetime, Jan Bleuland amassed a large collection of medical specimens of the human body, which he used for research. Part of this significant collection is still on display in the original wooden Bleulandkabinet in the Utrecht University Museum. The Bleulandkabinet contains an extensive collection of skeletons, embryos in alcohol and wax preparations of body parts. His pioneering preparations were acquired by Utrecht University by royal decree of King Willem I in 1815 and are still used as teaching material.
Giovanni Boccaccio was an Italian humanist scholar, writer and poet of the Early Renaissance.
Boccaccio was the son of a Tuscan merchant who sent him to Naples to study business and law. Giovanni revolved in aristocratic circles there and became acquainted with Petrarch's work. In Naples he wrote his first works of poetry, raising the poetry of Italian minstrelsy to literature. Returning to Florence in 1341, Boccaccio, in addition to the famous book of witty short stories "Decameron" (1348-1353), created many poems, allegories and prose works.
In 1350 at Bocaccio's house in Florence, he met Petrarch, which developed into a friendship. In the last years of his life he concentrated on scholarly works in Latin, including writing De montibus, silvis, fontibus, lacubus..., - this alphabetical list of mountains, forests, rivers and lakes was based on the writings of ancient poets. His other Latin works include the philosophical and historical De claris mulieribus (a collection of biographies of famous women, 1360-74) and De casibus virorum illustrium (On the Fates of Famous Men, 1355-74).
Giovanni Boccaccio had a significant influence on the development of all European culture through his work. Together with Petrarch, he laid the foundations of Renaissance humanism and raised popular literature to the level and status of the ancient classics.
Anicius Manlius Severinus Boethius, commonly known as Boethius (Latin: Boetius), was an Italian senator, consul, magister officiorum, historian, and philosopher of the Early Middle Ages. He was a central figure in the translation of the Greek classics into Latin, a precursor to the Scholastic movement, and, along with Cassiodorus, one of the two leading Christian scholars of the 6th century.
Joseph Georg Böhm was an Austrian astronomer, astrophysicist, cartographer, mathematician, and educator.
At the University of Prague, Böhm attended lectures in mathematics, physics, astronomy, and, after receiving his doctorate, became an assistant at the Vienna Observatory under Joseph Johann von Littrow. He then worked at the observatory at Othen and taught mathematics at the University of Salzburg. In 1839 he was appointed professor of mathematics and practical geometry at the University of Innsbruck, and in 1848 he was elected its rector. In 1852 Böhm was appointed director of the Prague Observatory and professor of theoretical and practical astronomy at the University of Prague.
Georg Böhm published several significant astronomical papers on solar observation. He is the creator of several instruments for astronomical measurements and observations, and he designed the Uranoscope and Universal Gnomon for amateur astronomical observations for the general public. As a member of the commission for the repair of the Prague Astronomical Clock, which he joined in 1865, he wrote a detailed description of it in the work Beschreibung der alterthümlichen Prager Rathausuhr. In addition to astronomy and its popularization, he was also involved in agriculture, economics, and geodesy. One of his important works is Ballistic Experiments (1865).
Bernard Bolzano, full name Bernard Placidus Johann Nepomuk Bolzano, was an Italian-born Czech scientist, mathematician, logician, philosopher and theologian.
Bolzano graduated from the University of Prague and was immediately appointed professor of philosophy and religion at the university. Within a few years, however, Bolzano had already shown himself to be a free thinker with his teachings on the social costs of militarism and the needlessness of war. He called for a complete reform of the educational, social, and economic systems that would direct the nation's interests toward peace rather than armed conflict between states. In 1819, Bolzano was expelled from the university for his beliefs and thereafter turned his full attention to works on social, religious, philosophical, and mathematical issues.
Bolzano held advanced views on logic, mathematical quantities, limits, and continuity. He is the author of the first rigorous theory of real numbers and one of the founders of set theory. In his studies of the physical aspects of force, space, and time, he proposed theories opposed to those advanced by the German philosopher Immanuel Kant. His contributions to logic, in particular, established his reputation as the greatest logician of his time. Much of his work remained unpublished during his lifetime and was not widely disseminated until the late nineteenth and early twentieth centuries, when a number of his conclusions were reached independently.
Bolzano was multi-talented in various fields of science to which he made significant contributions. His published works include The Binomial Theorem (1816), A Purely Analytic Proof (1817), The Functional Model and the Scientific Model (1834), An Attempt at a New Statement of Logic (1837), and The Paradoxes of Infinity (1851).
Among other things, Bolzano was also a great philanthropist. Together with his friends and students, he supported the activities of almshouses, homes for the blind, loan banks for the working class, libraries, and elementary schools in rural areas.
Matthieu Bonafous was a prominent French botanist and agronomist.
Bonafous was an innovator in 19th century agronomy, specializing in technical farming, with a particular interest in corn and its economic importance as a food crop. He also studied mulberry trees and created new species for silkworm breeding, and wrote many scientific articles, including one on rice.
As a teacher, Matthieu Bonafous offered a traveling course based on direct contact with practitioners of scientific farming.
Filippo Bonanni or Buonanni was an Italian Jesuit scholar. His many works included treatises on fields ranging from anatomy to music. He created the earliest practical illustrated guide for shell collectors in 1681, for which he is considered a founder of conchology. He also published a study of lacquer that has been of lasting value since his death.
Aimé Bonpland, born Aimé Jacques Alexandre Goujaud, was a French and Argentine natural scientist, traveler, physician, and botanist.
Bonpland became famous for his participation in an expedition to the Americas. Together with the explorer Alexander von Humboldt, he traveled through much of the American territory, from Cuman to the United States, passing through Colombia, Ecuador, Peru, Mexico, and Cuba, in addition to Venezuela. In all these places he did a great deal of botanical work, describing and collecting six thousand species of American plants, many of which were new. The scientist made them known in Europe after his return in 1804, publishing several scientific papers. Four years later, Bonpland was appointed botanist of the Empress's Garden.
After more years, he returned to Buenos Aires and continued numerous botanical, zoological, and medical studies in various regions of South America. Bonpland sent plants to the Museum of Natural History in Paris and maintained correspondence with its naturalists.
Giovanni Alfonso Borelli was an Italian universalist scientist of the 17th century Scientific Revolution, the founder of biomechanics.
He studied mathematics under Benedetto Castelli (1577-1644) in Rome. In the 1640s Borelli was appointed to the chair of mathematics at the University of Messina and at Pisa in 1656. After 12 years at Pisa and numerous disputes with colleagues, Borelli left the university. In 1667 Borelli returned to the University of Messina, where he engaged in literary and historical studies, studied the eruption of the volcano Etna, and continued to work on the problem of muscular movement of animals and other bodily functions according to the laws of statics and dynamics. In 1674 he was accused of participating in a conspiracy to liberate Sicily from Spain and fled to Rome.
Borelli is known primarily for his attempts to explain muscular movement and other bodily functions according to the laws of statics and dynamics. His best-known work is De Motu Animalium (1680-81; "On the Motion of Animals"). Borelli calculated the forces required for balance in the various joints of the human body, long before Newton published his Laws of Motion. Borelli was the first to realize that musculoskeletal levers increase motion, not force, so muscles must produce much greater forces than those that resist motion. He was also one of the first microscopists: he made microscopic studies of blood circulation, nematodes, textile fibers, and spider eggs. Borelli also authored works on physics, medicine, astronomy, geology, mathematics, and mechanics.
Ismaël Boulliau (Boulliaud), also known as Ismael Bullialdus, was a French astronomer and mathematician who followed the teachings of Copernicus.
Boulliau worked as a librarian for many years and had the opportunity to study the scientific works of Copernicus, Galileo, and Kepler, and as a result became a strong supporter of the heliocentric system of the world. Boulliau was also intimately acquainted with Huygens, Gassendi, Pascal and other prominent scientists of the time, and he translated many works from Greek into Latin.
Boulliau's main astronomical work, published in 1645, was Astronomia philolaica (Astronomy of Philolaus, named after the ancient Greek Pythagorean philosopher Philolaus, who promoted the idea of the motion of the Earth). In it, he supported Kepler's first law that the planets move on ellipses, and provided new evidence for this. Isaac Newton, in Book III of The Mathematical Beginnings of Natural Philosophy, relies on measurements of the magnitudes of planetary orbits determined from observations by Kepler and Boulliau.
Boulliau was also interested in history, theology, classical studies, and philology. He was active in the Republic of Letters, an intellectual community whose members exchanged ideas.
Joachim Bouvet was a French Jesuit monk and missionary who worked in China.
Joachim Bouvet was one of six Jesuit mathematicians chosen by Louis XIV to travel to China as his envoys and work as missionaries and scholars. In 1687 in Beijing, Bouvet began this work, especially in mathematics and astronomy, and in 1697 the Chinese emperor Kangxi (1654-1722) sent him as ambassador to the French king. Kangxi expressed his wish that Bouvet should bring more missionary scientists with him. Thus, in addition to his scholarly work, Bouvet was also an accomplished diplomat and served as a liaison between the Chinese Emperor Kangxi and King Louis XIV of France.
Bouvet brought to France a manuscript describing Kangxi's life with an eye for diplomatic subtleties, as well as a collection of drawings depicting graceful Chinese figures in traditional and ceremonial dress. The first French edition of The Historical Portrait of the Emperor of China was published in Paris in 1697, and was subsequently translated and published in other languages. And Bouvet returned to China in 1699 with ten new missionaries and a collection of King Louis XIV's engravings for Emperor Kangxi. He remained in China for the rest of his life.
Tycho Brahe, born Tyge Ottesen Brahe, more commonly called Tycho, was a prominent Danish astronomer, astrologer, and alchemist of the Renaissance.
As a young man he traveled extensively throughout Europe, studying in Wittenberg, Rostock, Basel, and Augsburg and acquiring mathematical and astronomical instruments. In 1572 Tycho unexpectedly even for himself discovered a new star in Cassiopeia, and the publication of this turned the young Dane into an astronomer of European reputation. For further astronomical research he established an observatory and gathered around him modern progressive scientists.
Besides practicing astronomy, Tycho was an artist, scientist, and craftsman, and everything he undertook or surrounded himself with had to be innovative and beautiful. He even founded a printing house to produce and bind his manuscripts in his own way, and he perfected sanitary ware for convenience. His development of astronomical instruments and his work in measuring and fixing the positions of the stars laid a solid foundation for future discoveries.
Tycho's observations - the most accurate possible before the invention of the telescope - included a comprehensive study of the solar system and the precise positions of more than 777 fixed stars. What Tycho accomplished using only his simple instruments and intellect remains a remarkable achievement of the Renaissance.
Georg Braun was a German topographical geographer, cartographer and publisher.
Braun was the editor-in-chief of the Civitates orbis terrarum, a groundbreaking atlas of cities, one of the major cartographic achievements of the 16th century. It was the first comprehensive and detailed atlas, with plans of the world's famous cities and bird's-eye views, and became one of the best-selling works of the time.
The book was prepared by Georg Braun in collaboration with the Flemish engraver and cartographer Frans Hoogenberg. Braun, as editor-in-chief, acquired tables, hired artists, and wrote the texts. They drew on existing maps as well as maps based on drawings by the Antwerp artist Joris Hofnagel and his son Jacob. Other authors include Pieter Bruegel the Elder (c. 1525-1569), Jacob van Deventer (c. 1505-1575), and more than a hundred other artists and engravers.
Mathurin Jacques Brisson was a French zoologist, ornithologist, naturalist and physicist, a member of the Academy of Sciences.
He is known for his published works in natural history: Le Règne animal ("The Kingdom of Animals", 1756) and Ornithologie ("Ornithology", 1760), in which he described 1,500 species of birds grouped into 115 genera, twenty-six orders, and two classes. Brisson was one of the first to come close to the concept of "type" in zoology, although he does not use the term, but his classification was used for about 100 years. He translated a number of important books on zoology for his time into French.
Brisson's works in physics are related to the measurement of specific gravity of various bodies, the study of gases and refraction of light, mirrors, magnetism, atmospheric electricity, and barometers.
Giovanni Battista Brocchi was an Italian mineralogist, geologist and paleontologist.
Brocchi studied law at the University of Padua, but was seriously interested in natural sciences and mineralogy. In 1802, Brocchi became a teacher of natural history at the Brescia Gymnasium. Appointment in 1808 as inspector of mines in Milan gave him the opportunity to travel extensively in Italy, making extensive notes and collecting numerous samples. The fruits of these labors appeared in various publications, notably his "Treatise mineralogical and chemical on the iron mines of the department of Mella" (1808). He then obtained a position as inspector of mining in the newly created kingdom of Italy.
In 1811 Brocchi wrote a valuable essay entitled "Mineralogical Memoirs on the Fassa Valley in the Tyrol." He made his first extensive exploration of central Italy in 1811-1812, witnessed the eruption of Vesuvius, and was able to compare the condition of its crater before and after the eruption. But his most important work is Fossils of the Sub-Apennines with geological observations on the Apennines and adjacent soil (1814), which contains precise details of the structure of the Apennine ridge and an account of the fossilization of Italian Tertiary strata in comparison with existing species. Brocchi also wrote several significant works on biology.
In the fall of 1822 he sailed from Trieste to Egypt, whence he made excursions up the Nile and into Syria and Palestine. In 1826 he contracted the bubonic plague, of which he died. His last journals and collections are preserved at the Museo Civico in Bassano. In all, Brocchi published five voluminous books and about seventy articles in various journals.
Edward Browne was a British physician, president of the College of Physicians, traveler, historian and writer.
Edward was the eldest son of the famous British scientist Sir Thomas Browne (1605-1682), received a Bachelor of Medicine degree from Cambridge later and a Doctor of Medicine degree from Oxford, and became a member of the Royal Society. In addition to medicine, his subjects of study included botany, literature, and theology. He lived in London and traveled throughout Europe visiting museums, churches, and libraries (Italy, France, the Netherlands, and Germany). In 1673 he published an account of his travels in Eastern Europe, notable for its scrupulous accuracy.
Edward Browne also published two other works: a historical treatise and biographies of Themistocles and Sertorius. He was physician to King Charles II of England and left many manuscript notes on medicine. The chronicle of his journey through Thessaly is a unique and valuable source of information about the region in the second half of the 17th century. He was admitted to the College of Physicians in 1675 and served as its president from 1704 to 1708.
Patrick Browne was an Irish physician and historian, traveler, naturalist and botanist.
Patrick Browne studied medicine in Paris, graduated from the University of Reims, continued his studies in Leiden, and then worked as a doctor at St. Thomas' Hospital in London. Subsequently, he lived for many years in the Caribbean, in Antigua, Santa Cruz, Montserrat and Jamaica, where he practiced medicine. He devoted all his spare time to the study of the natural history of the island. In 1771, Brown returned to Mayo County.
In 1756, Brown published A Civil and Natural History of Jamaica, his most significant work in terms of Carl Linnaeus's botanical nomenclature, which included new names for 104 genera.
Victor Yakovlevich Bunyakovsky (Russian: Ви́ктор Я́ковлевич Буняко́вский) was a Russian mathematician, teacher, historian of mathematics, vice-president of the Academy of Sciences in 1864-1889. He made a significant contribution to number theory.
Eugène Burnouf was a French Orientalist scholar, linguist, and researcher of Buddhism in the mid-19th century.
Burnouf studied at the School of Law and the Collège de France. In collaboration with the Norwegian orientalist Christian Lassen, he published Essai sur le Pali (1826) in one of the languages of Indian Buddhism. He then undertook the decipherment of Zoroastrian manuscripts.
As professor of Sanskrit at the Collège de France (1832-1852), Burnouf made a significant contribution to the study of Zoroastrianism. He also made a Sanskrit edition and French translation of the important Hindu text Le Bhâgavata Purana (1840) and published a history of Buddhism (1845).
Carl Gustav Carus was a German painter of the first half of the 19th century. He is known as a landscape painter, as well as a scientist, physician (gynecologist, anatomist, pathologist, psychologist) and a major theorist of Romanticism in art.
Carus created idyllic landscapes depicting moonlit nights, mountains, forests, Gothic architecture and ruins. In his work, according to critics, he combined a romantic view of nature with the classical ideal of beauty, understood the beautiful as a triad of God, nature and man. Noteworthy are his small-format, spontaneously created landscape sketches with images of clouds. The master is the author of "Nine Letters on Landscape Painting" - one of the main theoretical works that laid the foundations of the German Romantic school of painting.
Augustin Louis Cauchy was a French mathematician and mechanic, military engineer, and founder of mathematical analysis.
Cauchy studied at the École Polytechnique and at the Paris School of Bridges and Roads. After becoming a military engineer, he went to Cherbourg in 1810 to work on harbors and fortifications for Napoleon's English invasion. Here he began independent mathematical research. Cauchy returned to Paris in 1813, and Lagrange and Laplace convinced him to devote himself entirely to mathematics. The following year he published a memoir on definite integrals, which formed the basis of the theory of complex functions. From 1816, Cauchy held professorships at the Faculty of Natural Sciences, the Collège de France, and the École Polytechnique in Paris.
Cauchy developed the foundation of mathematical analysis, and made enormous contributions to analysis, algebra, mathematical physics, and many other areas of mathematics. He almost single-handedly founded the theory of functions of a complex variable, which has extensive applications in physics. Cauchy's greatest contributions to mathematics are published primarily in three of his treatises, "Courses in Analysis at the Royal Polytechnic School" (1821), "Summary of Lessons on Infinitesimal Calculus" (1823), and "Lessons on the Application of Infinitesimal Values in Geometry" (1826-28). In all, Augustin Louis Cauchy wrote about 800 scientific articles.
Cauchy was a member of the Paris Academy of Sciences, the Royal Society of London, the St. Petersburg Academy of Sciences, and other academies.
Bonaventura Francesco Cavalieri (Latin: Bonaventura Cavalerius) was an Italian mathematician and a Jesuate. He is known for his work on the problems of optics and motion, work on indivisibles, the precursors of infinitesimal calculus, and the introduction of logarithms to Italy. Cavalieri's principle in geometry partially anticipated integral calculus.
Nicolas Chuquet was a 15th century French mathematician.
The exact dates of birth and death of this scientist are not known, nor are the places of birth. Chuquet received a Bachelor of Medicine degree from the University of Paris, went to Italy in the early 1470s, and around 1480 moved to Lyon, where he worked as a physician, mathematics teacher, and scribe. He is also known to have translated Latin works into French.
In 1484 he wrote his major algebraic work, the treatise Le Triparty en la Science des Nombres (The Science of Numbers in Three Parts), now considered one of the most original mathematical texts of the 15th century. At the time, arithmeticians lacked even the most basic notations for addition subtraction, multiplication, and division. Chuquet was one of the first to propose these symbols; he also introduced the names of large numbers into common use: billion, trillion, etc. In addition to general arithmetic and rules for calculating roots, the treatise contains a doctrine of equations and a collection of problems.
This treatise was published only in 1880, but the works of Nicolas Chuquet had a significant influence on the development of algebra, and they were consistently supplemented and expanded by scientists of the following generations.
Lucius Iunius Moderatus Columella was an ancient Roman author of books on agriculture.
As a young man he was a soldier and tribune in the Roman army, but then devoted himself entirely to farming in Italy. Fully extant are De re rustica in 12 books, Columella's second and more complete study of farming and village life, and De arboribus ("On Trees"), which was part of an earlier work. Both books are written in a clear, non-academic style, the author clearly trying to instill in the reader a love of farming and the simple life.
Columella in his writings sometimes quotes from the works of Cato the Elder and Marcus Terentius Varrone, which all together provide an important source of knowledge about life at the time. The book On Farming, published in 1745, is an English translation of Columella's De re rustica and De arboribus.
Caspar Commelin was a Dutch botanist and mycologist.
Caspar Commelin was trained as a medical doctor, practiced botanical science and worked on books that were left unfinished due to the death of his uncle, botanist Jan Commelin. Caspar was mainly interested in exotic plants.
Jan Commelin (Dutch: Jan Commelin or Jan Commelijn), also Johannes Commelin, was a Dutch botanist.
Jan Commelin is the son of the historian Isaac Commelin. He was a professor of botany and director of the Amsterdam Botanical Gardens. Jan Commelin wrote many scientific works on botany, notably compiling the first volume of descriptions of East and West Indian plants. The second volume was written by Jan's nephew, the botanist Caspar Kommelin, who expanded the earlier descriptions and added notes on African plants.
Nicolaus Copernicus (Polish: Mikołaj Kopernik) was a Polish and German scientist, astronomer, mathematician, mechanic, economist, and Renaissance canonist. He was the author of the heliocentric system of the world, which initiated the first scientific revolution.
Copernicus studied the humanities, including astronomy and astrology, at the University of Krakow and at the University of Bologna in Italy. Together with other astronomers, including Domenico Maria de Novara (1454-1504), he was engaged in observing the stars and planets, recording their movements and eclipses. At the time, medicine was closely related to astrology, as the stars were believed to influence the human body, and Copernicus also studied medicine at the University of Padua between 1501 and 1503.
Nicolaus Copernicus, based on his knowledge and observations, was the first to suggest that the Earth is a planet that not only revolves around the sun every year, but also rotates once a day on its axis. This was in the early 16th century when people believed the Earth to be the center of the universe. The scientist also suggested that the Earth's rotation explained the rising and setting of the Sun, the movement of the stars, and that the cycle of the seasons was caused by the Earth's rotation around itself. Finally, he correctly concluded that the Earth's motion in space causes the planets to move backwards across the night sky, the so-called retrograde direction.
Although Copernicus' model was not completely correct, it laid a solid foundation for future scientists, such as Galileo, who developed and improved mankind's understanding of the motion of celestial bodies. Copernicus completed the first manuscript of his book De Revolutionibus Orbium Coelestium (On the Rotation of the Celestial Spheres) in 1532. In it, the astronomer outlined his model of the solar system and the paths of the planets. However, he published the book only in 1543, just two months before his death, and dedicated it to Pope Paul III. Perhaps for this reason, and also because the subject matter was too difficult to understand, but the church did not finally ban the book until 1616.
Francis Harry Compton Crick was a British molecular biologist, biophysicist and neuroscientist. He won the Nobel Prize in Physiology and Medicine in 1962.
During World War II he had to work on developments for the military, and in 1947 he turned to biology at the Strangeways Research Laboratory, University of Cambridge. In 1949 he moved to the University Medical Research Council at Cavendish Laboratories. Using X-ray diffraction studies of DNA by biophysicist Maurice Wilkins (1916-2004) and X-ray diffraction images taken by Rosalind Franklin, biophysicist James Watson and Crick were able to construct a molecular model consistent with the known physical and chemical properties of DNA.
This achievement became a cornerstone of genetics and was regarded as one of the most important discoveries of 20th century biology. In 1962, Francis Crick, along with James Watson and Maurice Wilkins, won the Nobel Prize in Physiology or Medicine for determining the molecular structure of deoxyribonucleic acid (DNA), the chemical ultimately responsible for the hereditary control of life functions.
From 1977 until the end of his life, Crick served as professor emeritus at the Salk Institute for Biological Studies in San Diego, California, where he conducted research on the neurological basis of consciousness. He also wrote several books. In 1991, Francis Crick received the Order of Merit.
William Curtis was a British botanist and entomologist, editor of the oldest botanical publication in Great Britain.
Curtis became interested in natural history in his youth, and at the age of 25 had already published "Instructions for the Collection and Preservation of Insects", particularly butterflies. In 1779 he founded his own London botanical garden at Lambeth and published Flora Londinensis (1777-1798), a 6-volume work on urban nature.
In 1787 Curtis began publishing the later popular Botanical Magazine, which also featured hand-colored plates by artists. This magazine has changed its name several times over time, but is still continued by the Royal Botanic Gardens, Kew, as a publication for those interested in horticulture, ecology or botanical illustration. Interestingly, the magazine was entirely hand-colored until 1948.
Joao de Souza Freire de Araujo Borges Da Veiga was a Portuguese astronomer and climatologist.
This scientist is one of the authors of the manuscript Dialogo epistolar astronomico sobre o cometa apparecido em Lamego as da Abril e observado aze o dia 9. dao anno de 1766. The second author who signed this manuscript is Joze de Araujo Souza Freire Borges Da Veiga.
It is a Portuguese treatise on the 1766 comet (D/1766 G1 Helfenzrieder), which appeared in April of that year and was discovered on April 1 by Helfenzrieder, and independently by Messier, Cassini de Turi, and others. The treatise gives a detailed account of the observations made by the authors from an observatory located on Mount Queimada near Lamego, Portugal. The authors also provide a chronological catalog of previous observations of comets since 1500 and cite their numerous authors.
The authors of this treatise were the first known climatologists, as well as experienced astronomers in continental Portugal who made meteorological observations.
Leonardo da Vinci was an Italian polymath of the High Renaissance, celebrated as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. His remarkable abilities and innovative thinking made him an epitome of the Renaissance humanist ideal. Born in Vinci, near Florence, in 1452, Leonardo was educated in Florence by Andrea del Verrocchio, a renowned painter and sculptor. He began his career in Florence, later working in Milan, Rome, and France, where he died in 1519.
Da Vinci is revered for his artistic mastery, technological innovation, and scientific inquiry. Despite having fewer than 25 major works attributed to him, including several unfinished ones, his influence on Western art is profound. His magnum opus, the "Mona Lisa," housed in the Louvre Museum, Paris, is considered the world's most famous painting. "The Last Supper," his most reproduced religious painting, showcases his mastery of dramatic narrative and pictorial illusionism. Both paintings exhibit Leonardo's unique ability to convey complex human emotions and his innovative use of techniques like sfumato and chiaroscuro.
Leonardo's interests extended far beyond fine art. He was a visionary in multiple fields, including anatomy, physics, architecture, and mechanics. His notebooks reveal designs for machines like bicycles, helicopters, and military tanks, centuries ahead of their time. However, due to his diverse interests, he left many projects and paintings incomplete. Leonardo's final years were spent in France, where he continued his artistic and scientific pursuits until his death.
For collectors and experts in art and antiques, Leonardo da Vinci remains a figure of endless fascination. His works not only embody the pinnacle of Renaissance art but also provide insights into the era's scientific and philosophical inquiry.

John Dalton was a British scientist, chemist and physicist, naturalist, and pioneer in the development of modern atomic theory.
In the 1800s, he was the first scientist to explain the behavior of atoms in terms of weight measurements. Some of the tenets of Dalton's atomic theory proved to be false, but most of the conclusions remain valid to this day.
Problems with his own eyesight led Dalton to research and describe the visual defect he himself suffered from in 1794 - color blindness, later named color blindness in his honor.
Francesco de Bourcard was a Swiss-born Italian scholar, historian and publisher.
De Bourcard devoted about twenty years, from 1847 to 1866, to the production of a voluminous work, The Uses and Customs of Naples, to which he engaged a large number of contributors, both writers, artists, and engravers.
The first of the two volumes was published in 1853. The books depict the customs of the time, the typical characters of the people, their daily lives, and a wide range of popular and religious festivals. Hundreds of lithographs are accompanied by explanatory texts.
Jean Charlier de Gerson was a French academic, theologian, preacher and politician of the 14th and 15th centuries.
Jean Charlier de Gerson was Chancellor of the University of Paris from 1395 until 1415, and as such played a major role in the political troubles between the Duke of Orleans and the Duke of Burgundy, subsequently known as the Armagnacs and Burgundians, as well as in the crisis arising from the Great Western Schism.
Nicolas-Louis De la Caille was a French astronomer, abbot and educator.
He studied philosophy and theology, became an abbot, but the craving for science overpowered everything, and he studied astronomy on his own. In 1736, la Caille received a place at the Paris Observatory, in 1739 was appointed professor of mathematics at Mazarini-College in Paris and built his own observatory, where he conducted astronomical observations. In 1741 Lacaille was admitted to the Académie des Sciences.
La Caille was an outstanding astronomer: he observed more than 10,000 stars in the Southern Hemisphere and named 14 of the 88 constellations. In 1752, he made an astronomical expedition to the Cape of Good Hope, where he built an observatory and conducted a huge series of observations, including the discovery and cataloging of 42 nebulae. These studies led to la Caille being called "the father of southern astronomy," and his observations from South Africa of the Moon, Venus, and Mars, combined with similar observations already made in the Northern Hemisphere, led to the calculation of more accurate values for the distances to these bodies.
On his return to Paris two years later, in 1754, he resumed his post and taught at the school of Mazarin, continuing his work at the observatory of the College of Mazarini. Among his pupils was the great chemist Antoine Lavoisier. La Caille was a foreign honorary member of the St. Petersburg Academy of Sciences and a member of the Royal Society of London. His Coelum Australe Stelliferum ("Star Catalog of the Southern Sky") was published in 1763.
Juana Inés de la Cruz or Juana of Asbaje, real name Juana Inés de Asbaje Ramírez de Santillananota, was a Mexican poet, scholar, and writer of the Latin American colonial period and the Spanish Baroque, and a Jerónimo nun.
Juana Ramírez was born into a poor family (Spanish father and Creole mother) and from an early age showed a burning thirst for knowledge and giftedness, but as a woman she was almost entirely self-taught. By her teens, she had already learned Greek logic and taught Latin to young children. She also learned Nahuatl, an Aztec language spoken in Central Mexico, and wrote several short poems in the language. At the age of 16, the girl was introduced to the court, and her intelligence impressed even Viceroy Antonio Sebastian de Toledo, Marquis de Mancera, and in 1664 he invited her to serve as maid of honor.
In 1669, at the age of 21, she took her tonsure at the Convent of Santa Paula of the Hieronymite Order in Mexico City, where she remained a recluse for the rest of her life. In the convent, Sister Juana enjoyed exceptional freedom: she continued to socialize with scholars and senior members of the court, amassed one of the largest private libraries in the New World, as well as a collection of musical and scientific instruments. Her plays in verse, poetry, and compositions for state and religious festivals were frequently and successfully performed at the palace.
Sister Juana was an outstanding representative of Spain's Golden Age: she was the last significant writer of the Latin American Baroque and the first great exponent of colonial Mexican culture. Sister Juana wrote sonnets, romances, and ballads, drawing on a vast store of classical, biblical, philosophical, and mythological sources. She also composed moral, satirical, and religious texts, as well as many poems praising courtiers, but she also defended women's right to education.
At the end of her life, due to pressure from religious dogmatists, Sister Juana had to sell her extensive library of some 4,000 volumes and return to strict reclusiveness. In 1695, the plague struck the convent and, while caring for her sisters, Juana died of the disease at about the age of forty-four.
Today, Juana Inés de la Cruz is a national icon of Mexico and Mexican identity as a prominent writer of the Spanish-American colonial period. The former convent where she lived is a center of higher education, and her image adorns Mexican currency.
Estienne de la Roche, also known as Estienne de Villefranche, was a French mathematician.
He is known for having taught mathematics in Lyon for 25 years as a professor of mathematics. In 1520 he published the Arismatics, considered at the time the best reference book on algebra.
René Descartes was a French philosopher, mathematician, and natural scientist who is considered the founder of modern philosophy.
Descartes was a very versatile scientist: besides numerous philosophical reflections, he wrote works on optics, meteorology and geometry. Contemporaries noted his extensive knowledge in many sciences. Descartes owns the famous saying "I think, therefore I exist" (best known in the Latin formulation "Cogito, ergo sum", although it was originally written in French: "Je pense, donc je suis").
He developed a metaphysical dualism that radically distinguished between mind, whose essence is thought, and matter, whose essence is extension in three dimensions. Descartes' metaphysics is rationalistic, based on the postulation of innate ideas of mind, matter, and God, but his physics and physiology, based on sense experience, are mechanistic and empirical.
Unlike his scientific predecessors, who felt a holy awe at the incomprehensibility of the divine essence of the universe, Descartes admired the ability of the human mind to understand the cosmos and to generate happiness itself, and rejected the view that human beings were inherently unhappy and sinful. He believed that it was inappropriate to pray to God to change the state of things and the world; it was much more productive to change oneself.
Denis Dodart was a French botanist, naturalist and physician.
Dodart studied at the University of Paris, received a doctorate in medicine and was already in his youth known for his erudition, eloquence and open-mindedness. In 1673 he was elected to the French Academy of Sciences.
He is known for his early studies of plant respiration and growth. Dodart collaborated with the French engraver Nicolas Robert to illustrate his botanical works.
Dru Drury was a British entomologist and collector.
Dru Drury was an avid collector and his entomological collection totals 11,000 specimens. Drury corresponded extensively with entomologists from all over the world, from India to Jamaica to America, and bought any insects for 60 cents from officers of merchant ships arriving from afar. He even supplied travelers with a pamphlet of collecting instructions. It was through this work that Drury amassed most of his collection. From 1770 to 1787 he published three volumes on entomology, Illustrations of Natural History, with over 240 drawings of exotic insects.
Drury was president of the Society of Entomologists of London from 1780 to 1782, and a member of the Linnaean Society.
Johann Dryander, born Johann Eichmann, was a German medical anatomist, mathematician and astrologer.
He studied anatomy and medicine at the University of Paris and the University of Erfurt, and in 1535 became professor of medicine at the University of Marburg. A year later, Dryander performed two public autopsies, making the first illustrated description of the dissection of the human brain. Dryander titled his book Anatomiae, hoc est, corporis humani dissectionis pars prior ("Anatomy, that is, the dissection of the human body, part one," suggesting a sequel, which, however, did not follow.
His work made a significant contribution to the development of modern anatomy. Toward the end of his life, Dryander also dabbled in astrology and mathematics.
Charles-Frederic Dubois was a Belgian naturalist, artist and author of books on birds and butterflies.
Based on the results of his study of birds and scales of Belgium, Academician Dubois wrote Planches colorées des oiseaux de l'Europe ("Colored Plates of Birds of Europe") and Catalog systématique des Lépidoptères de la Belgique ("Systematic Catalog of Scales of Belgium"), which after his death was completed by his son Alphonse Joseph Charles Dubois (1839-1921).
Albrecht Dürer, born on May 21, 1471 in Nuremberg, Germany, is widely regarded as the greatest German Renaissance painter. His contribution to painting and engraving is quite significant and has left a notable mark on the art world. Dürer's early life was spent in Nuremberg, a city that played a crucial role in his development as an artist and was also the site of his death on April 6, 1528. He was the son of the goldsmith Albrecht Dürer the Elder, from whom he initially learned the basics of drawing and metalworking.
Dürer's work is characterized by a combination of Gothic elements with the emerging Renaissance style, which is evident in his woodcuts and engravings. His oeuvre encompasses many themes, including religious works, altarpieces, portraits, and self-portraits. His outstanding prints, such as The Knight, Death and the Devil (1513), St. Jerome in his Study (1514) and Melencolia I (1514), are known for their intricate detail and artistic skill. Dürer was also one of the earliest European landscape painters, as evidenced by his watercolor paintings.
Equally significant are his theoretical writings on mathematics, perspective, and ideal proportions in art. Dürer was not only an artist but also a keen intellectual, his interests encompassing various aspects of culture and science. He served as court painter to Holy Roman Emperors Maximilian I and Charles V, completing several significant art projects for them. Dürer's keen mind and versatile interests brought him into contact with the most prominent figures of his time, including theologians and scientists of the Reformation era.
Dürer's self-portraits are particularly famous, demonstrating not only his artistic skill but also his self-awareness and personal style. These portraits attest to his growing success and confidence as an artist. Dürer's legacy is immense; he influenced not only the art of his time, but also left an indelible mark on the history of European art.

Albert Einstein was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics. His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius".
Euclid (Greek: Εὐκλείδης) was an ancient Greek mathematician active as a geometer and logician. Considered the "father of geometry", he is chiefly known for the Elements treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. His system, now referred to as Euclidean geometry, involved new innovations in combination with a synthesis of theories from earlier Greek mathematicians, including Eudoxus of Cnidus, Hippocrates of Chios, Thales and Theaetetus. With Archimedes and Apollonius of Perga, Euclid is generally considered among the greatest mathematicians of antiquity, and one of the most influential in the history of mathematics.
Leonhard Euler was the greatest mathematician of the 18th century and history in general.
Euler brilliantly graduated from the University of Basel and entered the St. Petersburg Academy of Sciences, then began to work at the Berlin Academy, and later to lead it. In 1766, the scientist received an invitation from the Russian Empress Catherine II and again came to St. Petersburg to continue his scientific work.
Here he published about 470 works in a wide variety of fields. One of them is a large-scale work "Mechanics" - an in-depth study of this science, including celestial mechanics. Euler by that time was practically blind, but continued to be actively engaged in science, in the records he was helped by his son Johann Albrecht and stenographers. Leonhard Euler made many fundamental discoveries that brought great benefit to mankind.
His massive contribution to the development of mathematics, mechanics, physics and astronomy cannot be overestimated, and his knowledge in the most diverse branches of science is admirable. During his lifetime, he published more than 850 works that contain in-depth studies of botany, chemistry, medicine, ancient languages, and music. Euler held membership in many academies of science around the world.
Admiral Edward Ratcliffe Garth Russell Evans, 1st Baron Mountevans was a Royal Navy officer and Antarctic explorer.
Evans was seconded from the Navy to the Discovery expedition to Antarctica in 1901-1904, when he served on the crew of the relief ship, and afterwards began planning his own Antarctic expedition. However, he suspended this plan when offered the post of second-in-command on Robert Falcon Scott's ill-fated Terra Nova expedition to the South Pole in 1910-1913, as captain of the expedition ship Terra Nova. He accompanied Scott to within 150 miles of the Pole, but was sent back in command of the last supporting party. On the return he became seriously ill with scurvy and only narrowly survived.
Girolamo Fabrici d'Acquapendente, also known as Girolamo Fabrizio or Hieronymus Fabricius, was an Italian anatomist and surgeon and the founder of embryology. The Latinised form of his name, under which his works can be found, is Hieronymus Fabricius (ab Aquapendente).
Wilhelm Fabry von Hilden or Fabricius von Hilden (Latin: Fabricius Hildanus) was a German and Swiss Renaissance physician and surgeon, the founder of scientific surgery.
In 1576 he began a four-year apprenticeship as a surgeon with a barber in Neuss. Surgery at that time was considered the craft of bath and barbers; surgeons or wound doctors treated wounds, broken bones, inflammations, and many other ailments. After completing his apprenticeship, Fabry worked for five years as an assistant wound surgeon to Cosmas Slot (died 1585) at the court of Duke Wilhelm V in Düsseldorf. To expand his anatomical knowledge, Fabry constantly dissected and prepared cadavers. In later years, he also encouraged his students to do so and conducted public autopsies to draw attention to the importance of anatomical knowledge. He also made it a habit to do practice procedures on a cadaver before surgery.
In 1615 Fabry was appointed city physician of Bern. Here he wrote several books on gunshot wounds. In 1623 the versatile physician published a small book, "Christian and Good-Hearted Caution against Drunkenness," which he republished in more detail the following year under the title Christlicher Schlafftrunck. Fabry's most important surgical treatise was Observationem et curationem chirurgicam centuriae sex ("Six hundred surgical observations and cures"), first published in 1606. This compilation remained the most important book of German surgery until Lorenz Heister. It describes new surgical methods and surgical instruments for the treatment of amputations, nasal polyps, bladder stones, dropsy, hernias, ascites, etc., etc., etc.
For centuries, Fabricius remained one of the most respected surgeons not only in Germany and Switzerland, but throughout Europe. Among his many accomplishments in the field of surgery may be enumerated his innovation in the amputation of the thigh, for which he invented a special tourniquet; the excision of involved axillary glands in breast cancer; the first classification of burns into three degrees with the appropriate treatment for each variety; and the first description of a medical field chest for military purposes.
Although in his later years Fabritius had already given up practicing medicine, he continued to write medical papers and maintain an active scientific correspondence until his death. He authored some 20 medical books. It was his surgical works, translated into German, French, Latin, English and Dutch, that ensured his recognition centuries later.
Gabriele Falloppio was an Italian physician and anatomist of the Renaissance.
Originally a priest, Falloppio soon left for Ferrara to study medicine and was later appointed anatomy professor there, and in 1548 he became head of the anatomy department at Pisa. Three years later he accepted the offer of the Venetian Senate to become professor of anatomy, surgery, and botany at Padua, where he remained for the rest of his life. It was in this city that he made his most famous discoveries, was director of the famous botanical garden, and wrote two medical textbooks.
He also gained a reputation as an excellent teacher and lecturer, attracting many Italian and foreign students to the medical faculty of the University of Padua. As a physician, he made a thorough study of the clinical aspects and treatment of syphilis, and proposed the condom as a defense against venereal disease.
Falloppio was a versatile scientist and an able physician and surgeon, describing, among other things, the semicircular canals, the cuneiform sinuses, the trigeminal, auditory and lingual pharyngeal nerves, the canal of the facial nerve, and the fallopian tubes, named Fallopian tubes in his honor. Falloppio described his discoveries in his three-volume work Opera genuina omnia, published in Frankfurt in 1600 and in Venice in 1606.
Michael Faraday was a British physicist and chemist, explorer and experimenter.
Faraday, because of his family's poverty, was unable to receive a formal education, but at the bookbinding shop in London where he worked, he read many books, including encyclopedias and textbooks on chemistry and physics. He persevered in self-education, attending hearings at the City Philosophical Society and later lectures by Sir Humphry Davy at the Royal Institution, who as a result took the able student on as an apprentice. In 1825 he replaced the seriously ill Davy in the management of the laboratory of the Royal Institution.
In 1833 Faraday was appointed to a research chair of chemistry created especially for him, where, among other achievements, the scientist liquefied various gases, including chlorine and carbon dioxide. His study of heating and lighting oils led to the discovery of benzene and other hydrocarbons, and he experimented extensively with various steel alloys and optical glasses. Faraday was an excellent experimentalist who presented his ideas in simple language. He is best known for his contributions to the understanding of electricity and electrochemistry. The concepts behind electromagnetic induction, diamagnetism, and electrolysis were some of his most important discoveries. His electromagnetic research formed the basis of the electromagnetic equations that James Clerk Maxwell developed in the 1850s and 1860s.
Between 1831 and 1855, Faraday read a series of 30 papers before the Royal Society, which were published in his three-volume Experimental Investigations in Electricity. His bibliography numbers some 500 printed articles. By 1844 he had been elected a member of some 70 scientific societies, including the St. Petersburg Academy of Sciences.
Giovanni Battista Ferrari was an Italian Jesuit scholar, professor of Oriental languages and botanist.
Giovanni Ferrari had linguistic abilities and at the age of 21 knew Hebrew well, spoke and wrote Greek and Latin perfectly, and learned Syriac. He became professor of Hebrew and rhetoric at the Jesuit College in Rome and edited a Syriac-Latin dictionary in 1622.
Ferrari always showed great interest in the systematics and classification of fruits. He was appointed head of the chair of Hebraistics at the College of Rome and held this position for 28 years. In 1623, Ferrari became horticultural advisor to the family of Pope Urban VIII at the Palazzo Barberini, which soon became famous for its rare plants, including orange trees. Ferrari later wrote the first book on citrus trees, equating them to the mythical golden apples of the Hesperides conquered by Hercules. Orange trees became an important element of Baroque gardens, symbolizing the rewards earned by the magnanimous prince. The scientist also described the medicinal properties of citrus fruits.
In 1633, the first treatise on floriculture, De florum cultura, was published. In it, Ferrari describes garden layout with contemporary examples, flower specimens and their cultivation, and general horticulture.
Sir John Forrest was an Australian naturalist, traveler and politician.
He worked as a surveyor and led several exploratory pioneering expeditions to western Australia. On his second voyage in 1870-1871, Forrest made an instrumental survey of the entire southwest coast of Australia from Perth to Adelaide. He later served as Australia's Minister for Defense, and as the first Premier of Western Australia (1890-1901), Forrest sponsored the construction of public works and negotiated the state's entry into the Commonwealth of Australia in 1901.
Joseph Fourier, full name Jean-Baptiste Joseph Fourier, was a French mathematician and physicist and historical Egyptologist.
Fourier famously accompanied Napoleon Bonaparte on his Egyptian expedition in 1798 as a scientific advisor and was appointed secretary of the Institute of Egypt. During the occupation of Egypt, Fourier worked in the French administration, supervised archaeological excavations, and worked to shape the educational system.
But the main thing in Fourier's life was science. Back in France, he studied the mathematical theory of heat conduction, established the partial differential equation governing heat diffusion, and solved it using an infinite series of trigonometric functions. Fourier showed that heat diffusion obeyed simple observable physical constants that could be expressed mathematically. His work The Analytic Theory of Heat (1822) had a great influence on the development of physics and pure mathematics.
Joseph Fourier was a member of the Paris Academy of Sciences, the French Academy, a foreign honorary member of the St. Petersburg Academy of Sciences, and a member of the Royal Society of London.
igmund Freud, born Sigismund Schlomo Freud, was an Austrian psychologist, psychiatrist and neurologist, the founder of psychoanalysis.
He graduated from the medical faculty of the University of Vienna, was engaged in self-education and numerous, cutting-edge for his time studies of the human psyche. The resulting psychoanalysis he created was both a theory of the human psyche, a therapy to alleviate its ills, and a tool for interpreting culture and society. Freud's psychoanalysis had a significant impact on psychology, medicine, sociology, anthropology, literature and art in the twentieth century.
Despite the sometimes harsh criticism of virtually all of his ideas and teachings, which continues almost a century after his death, Freud remains one of the most influential intellectual figures of our time.
Christian Friedrich Freyer was a German entomologist.
According to contemporaries, Freyer was a venturesome and tireless collector of scales. He studied and first described 245 species of butterflies, including 193 species of nocturnal moths and 52 species of day butterflies. Freyer's importance as a field entomologist becomes evident from his work Die Falter um Augsburg ("Butterflies in the vicinity of Augsburg"). In it he lists 1,091 species. Freyer also created an international network between renowned European entomologists and involved them in his work.
Gemma Frisius, born Jemme Reinerszoon Frisius, was a Dutch mathematician, physician, cartographer, philosopher, engraver, and master of astronomical instruments.
He taught mathematics and medicine at the University of Leuven and applied his mathematical knowledge to astronomy, geography, and map-making. Frisius participated in the creation of the latest globes and used mathematics in geodesy and navigation in new ways and invented or improved many instruments, including the cross staff, the astrolabe, and the astronomical rings (also known as "Gemma rings"). He ran a workshop for making such instruments.
Frisius is credited with being one of the founders of the Dutch school of cartography.
Leonhart Fuchs was a German humanist scientist, botanist, and physician.
Fuchs received a humanistic education under Catholic guidance, but later became a Protestant. He studied medicine and became a professor in Tübingen. He was most interested in the medicinal properties of plants. Well acquainted with the Greek and Latin classics and an excellent observer, he gave precise descriptions, and his beautiful engravings of plants established the tradition of depicting plants with precise illustrations and in alphabetical order.
In 1542 Fuchs published his most important work, De Historia Stirpium Commentarii Insignes (Famous Commentaries on the History of Plants). The book was a great success, especially because of the magnificent woodcuts and the 487 plants, which were described for the first time in such a systematic form. De Historia Stirpium survived several editions and was translated into Dutch and German.
Galileo Galilei was an Italian naturalist, physicist, mechanic, astronomer, philosopher, and mathematician.
Using his own improved telescopes, Galileo Galilei observed the movements of the Moon, Earth's satellites, and the stars, making several breakthrough discoveries in astronomy. He was the first to see craters on the Moon, discovered sunspots and the rings of Saturn, and traced the phases of Venus. Galileo was a consistent and convinced supporter of the teachings of Copernicus and the heliocentric system of the world, for which he was subjected to the trial of the Inquisition.
Galileo is considered the founder of experimental and theoretical physics. He is also one of the founders of the principle of relativity in classical mechanics. Overall, the scientist had such a significant impact on the science of his time that he cannot be overemphasized.
William Gilbert was a British physicist and medical scientist famous for pioneering the study of magnetic and electrical phenomena.
After receiving a medical degree, Gilbert settled in London and began his research. In his major work De Magnete, Magneticisque Corporibus, et de Magno Magnete Tellure (On Magnetic Stones and Magnetic Bodies and the Great Magnet of the Earth), published in 1600, the scientist describes in detail his studies of magnetic bodies and electric attraction.
After years of experimentation, he came to the conclusion that the compass arrow points north-south and downward because the Earth acts as a rod magnet. He was the first to use the terms electric attraction, electric force, and magnetic pole. Gilbert came to believe that the Earth rotates on its axis and that the fixed stars are not all the same distance from the Earth, and believed that the planets are held in their orbits by magnetism.
Johannes Goedaert was a Dutch naturalist, entomologist and artist.
Goedaert was one of the authors on entomology and the first to write about insects in the Netherlands and Europe, based on his own observations and experiments between 1635 and 1667. In 1660, Goedaert published the first of three volumes collectively titled Metamorphoses and History of Nature, the last volume appearing in 1669.
Goedaert's work is valuable in that for the first time he used his own drawings instead of woodcuts to illustrate his insects, and they are of noticeably higher quality than those in Moffett's volume. Goedaert was a talented and observant artist and draughtsman, and he used magnifying glasses but preferred to draw insects at life-size. The book depicts detailed phases of insect growth, including their metamorphosis. The scientist not only described the process of their development, but also described and sketched the various stages that insects go through during their life cycle.
