médecine et sciences
Johann Friedrich Meckel the Younger was a German anatomist, biologist and professor of anatomy.
Meckel came from a family of physicians; his grandfather and father were physicians and anatomists and had their own anatomical museum at home. Meckel studied medicine at the universities of Halle and Göttingen, writing his doctoral dissertation on congenital anomalies of the heart. As a pathologist, he specialized in the study of congenital malformations and aspects of lung and blood vessel development. He also described Meckel's diverticulum, which he discovered during a pathologic examination, and became the founder of the science of teratology.
After Napoleon's occupation, the University of Halle reopened in May 1808, and Meckel was appointed professor of surgery, normal and pathological anatomy, and obstetrics. He taught throughout his life, continued to conduct research in pathology, and collected specimens for his collection. The scientist was the author of numerous articles and several multi-volume treatises, including one on pathologic anatomy and an atlas depicting human anomalies. His principal labors were devoted to the comparative morphology of vertebrates. In 1810 he completed the translation of Cuvier's (1769-1832) five-volume Leçons d'anatomie Comparée from French into German.
Meckel was a member of the German Academy of Naturalists "Leopoldina," a corresponding member of the Paris Academy of Sciences, and a foreign member of the Royal Society of London.
Samuel Thomas von Soemmering was a German physician, anatomist, anthropologist, paleontologist, physiologist and inventor.
He studied medicine at Göttingen, where he received his doctorate, and in the same year became professor of anatomy at Kassel, then at Mainz. Among Soemmering's contributions to biology are the discovery of the macula in the retina of the human eye, studies of the brain, lungs, nervous system, and embryonic malformations, and he published many papers in the fields of neuroanatomy, anthropology, and paleontology. He was the first to give a reasonably accurate account of the structure of the female skeleton.
Soemmering also worked on fossil crocodiles and pterodactyls, which at the time were called ornithocephalians. In addition, Soemmering dabbled in chemistry, astronomy, philosophy, and various other fields of science. Among other things, he investigated the refinement of wines and sunspots, and designed a telescope for astronomical observations. In 1809, Soemmering developed a sophisticated telegraph system based on electrochemical current, which is now preserved in the German Science Museum in Munich.
Charles Robert Darwin was an English naturalist, geologist, and biologist, widely known for contributing to the understanding of evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.
Bernard Palissy was a French natural scientist, painter, ceramicist and sculptor, geologist and writer of the French Renaissance.
Born into a family of artisans, Palissy apprenticed with his father as a glass artist and traveled throughout southwestern France comprehending pottery and studying geology. Today he is best known for his amazing lead-glazed pottery with images of various animals and people. After seeing a white glazed cup, probably of Chinese porcelain, in the 1540s, he set out to learn the secrets of its manufacture. His early research is described in De l'art de la terre. Although Palissy never succeeded in reproducing what he saw, his experiments gave him a thorough knowledge of the chemical compositions of minerals.
From 1575 in Paris, Palissy gave public lectures on natural history, which were published as Discours admirables (1580). In this treatise, Bernard Palissy touches on an incredibly wide range of subjects, from the techniques of ceramics, metallurgy and chemistry to hydrology, geology and fossils. He correctly identified fossils as the remains of ancient life. This work reveals him as a writer and scientist, a creator of modern agronomy and a pioneer of the experimental method, with scientific views generally more advanced than those of his contemporaries.
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.
Jean Rey was a French chemist and physician.
Rey received a Master of Arts degree from the Academy of Montauban, then a doctorate from the University of Montpellier, and worked as a physician in his hometown of Le Bug. He was also engaged in chemical research, corresponded with R. Descartes, M. Mersenne and others.
Jean Rey was the first to express the idea of conservation of mass as applied to chemical reactions. While conducting experiments in his brother's forge, he discovered that the mass of lead and tin increases with calcination. The researcher explained this based on the assumption that air has mass and that lead and tin combine with air during calcination. In 1630 Rey published a treatise on this topic, "Experiments to find the reasons for the increase in the weight of tin and lead during calcination". As can be seen from the treatise, he realized that substances are made up of particles. His discovery of the weight of air also made possible the invention of the Torricelli barometer in 1643. Jean Rey also developed a device called the thermoscope, a precursor to the thermometer.
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.
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.
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.
Marco Aurelio Severino was an Italian surgeon, anatomist and zoologist, one of the founders of comparative anatomy.
From childhood Severino studied Latin, Greek, rhetoric, poetry and law in various schools in Calabria, then continued his studies in Naples, soon moving from law to medicine. In Naples he met Tommaso Campanella, who had a great influence on the formation of his worldview. After receiving a medical degree in Salerno in 1606, he studied surgery in Naples with Giulio Jasolino. In 1615 Severino was appointed the first surgeon at Ospedale degli Incurabili. Severino made significant contributions to the transformation of naturophilosophy, medical and surgical practice, to which much of his printed work is devoted.
Severino's main contribution, however, lies in his anatomical works, especially the Zootomia Democritea. This work may be called the earliest comprehensive treatise on comparative anatomy. Severino is considered one of the pioneers of comparative anatomy.
Severino's cultural interests extended far beyond medicine. He corresponded with many prominent physicians and scientists of his time, including William Harvey and John Houghton in England, Thomas Bartolin and Ole Worm in Denmark, J.G. Volkamer and Johannes Wesling in Germany, and Campanella, Jasolino, and Tommaso Cornelio in Italy. Severino was tried by the Inquisition for allegedly unorthodox religious and philosophical views, but was eventually acquitted. He died of the plague in Naples.
Girolamo Franzosi was an Italian physician and philosopher.
He was born in Polpenazza (now Polpenazze del Garda), near the Lombard lakeshore, in the late sixteenth and early seventeenth centuries. Franzosi was a student at Padua and became a convinced Aristotelian. He opposed the anatomists of the Neoteric Academy, which represented the new trends of medicine in Verona in contrast to the Galenic tendencies of traditional medicine.
Franzosi's other works, written under the influence of Girolamo Cardano and Agostino Nifo, deal with such wide-ranging topics as dreams, prophecies, imagination, and the medicinal properties of viper venom. He printed most of his works in Verona, calling himself "medicus and philosopher of Verona".
Jacques Guillemeau was a French pioneering surgeon, obstetrician and ophthalmologist.
Born into a family of prominent Orleans physicians, he received a classical education and moved to Montpellier at the age of 21 to study medicine. With the support of his father, a respected surgeon at the court of the French king, Jacques Guillemeau studied under the country's leading physicians. In 1569 Guimault moved to Paris, and in 1574 he succeeded his teacher and royal surgeon Ambroise Paré (1510-1590). Guillemeau assisted Dr. Paré during the war in France and Flanders (1576-1580), and from 1581 he performed surgical operations at the Hotel Dieu hospital in Paris.
During his long career, Dr. Guillemeau earned a reputation as a skilled and experienced surgeon, also publishing several works that gave him a prominent place in the medical community of his time. In 1584, Guillemeau published his "Treatise on Eye Diseases", and in 1585, his "Treatise on the Ailments of the Soul". In 1609, his groundbreaking book "Happy Childbirth in Women" was published. And his "Works on Surgery", written for young surgeons, were regularly reprinted until the middle of the 17th century.
Israël Spach (also Israelis Spachius) was a German and French physician, medical writer and teacher of medicine.
Spach studied at the University of Tübingen, receiving the degree of doctor of medicine, and from 1589 taught medicine and Hebrew at the University of Strasbourg, with the rank of professor of medicine. He was characterized by a high bibliographical education.
Spach was the author of a gynecological encyclopedia, Gynaeciorum sive de mulierum tum communibus, tum gravidarum, parientium, et puerperarum affectibus et morbis, published in Strasbourg in 1597. It was a very significant book for its time.
Israël Spach also wrote Nomenclator scriptorum medicorum..., published in Frankfurt in 1591, which was the first attempt at a bibliography on medical subjects. It was organized under very broad subject headings, with indexes of authors and subjects.
Chérubin of Orleans (French: Chérubin d'Orleans), born François or Michel Lasseré, was a French monk of the Order of the Friars Minor Capuchin, physicist, and optical instrument maker.
Cherubin was engaged in the study of optics and problems related to vision. He designed the first binocular telescope, as well as a special type of spectacle in which the lens was replaced by a short perforated tube. Many of his binoculars, binocular microscopes and telescopes survive today. Cheruben is also credited with modeling the eyeball to study the functioning of the ocular lens.
About his research and work, Cherubin of Orléans published in Paris the works La dioptrique oculaire (Dioptrique oculaire, 1671) and La vision parfaite (Perfect Vision, 1677).
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".
Voltaire, born François Marie Arouet, was a French philosopher-enlightener of the French Enlightenment, poet and writer, satirist, tragedian, historian and essayist.
Voltaire's long life fell on the last years of classicism and the eve of the revolutionary era, and in this transitional period his works and activities had a significant impact on the direction of European civilization. Through his critical freethinking and wit, Voltaire won the minds of many 18th century European rulers. To this day, he continues to enjoy worldwide fame as a courageous fighter against tyranny, bigotry, and cruelty.
Voltaire was an advocate of freedom of speech, freedom of religion and separation of church and state. He was a versatile and prolific writer in all literary forms, including plays, poems, novels, essays, histories, and scholarly expositions. In total, he wrote more than 20,000 letters and 2,000 books and pamphlets. Voltaire's most famous works are the tragic play Zaire, the historical study The Age of Louis XIV, and the satirical novella Candide.
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.

Gottfried Wilhelm Leibniz was a German philosopher and a prominent polymath in many fields of science.
Leibniz was a universal genius; he showed his talents in logic, mathematics, mechanics, physics, law, history, diplomacy, and linguistics, and in each of the disciplines he has serious scientific achievements. As a philosopher, he was a leading exponent of 17th-century rationalism and idealism.
Leibniz was a tireless worker and the greatest scholar of his time. In the fate of Leibniz, among other things, there is one interesting page: in 1697, he accidentally met the Russian Tsar Peter I during his trip to Europe. Their further meetings led to the realization of several grandiose projects in Russia, one of which was the establishment of the Academy of Sciences in St. Petersburg.
Gottfried Wilhelm Leibniz was also the founder and first president of the Berlin Academy of Sciences and a member of the Royal Society of London.
