Scientists 15th century
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.
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.
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.
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.

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.
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.
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.

Georgius Merula, also Giorgio Merlani di Negro or Georgius Merula Alexandrinus, was an Italian humanist scholar, philosopher, philologist and historian of the Renaissance.
He held the position of professor and taught in Milan and Venice. But became known for being the first to print the works of Plautus (1472), Scriptores rei rusticae, Cato, Varron, Columella, and Palladius (1472). He also published commentaries on parts of Cicero (especially De finibus), Ausonius, Juvenal, Curtius Rufus, and other classical authors. Merula also labored in historical research and described several significant battles.
Regiomontanus, real name Johannes Müller, was a 15th-century German astronomer and mathematician, one of the first printers.
The son of a miller, he entered the University of Leipzig at the age of 11 and later transferred to the University of Vienna. In 1452, Regiomontanus earned a bachelor's degree and then a master's degree. With his teacher, the mathematical astronomer Georg von Peyerbach (d. 1461), he spent the next years practicing astronomy and astrology, including observations of eclipses and comets, making astronomical instruments, and compiling horoscopes for the court of Holy Roman Emperor Frederick III.
Regiomontanus was also seriously involved in mathematics, publishing his major work on trigonometry, On All Kinds of Triangles (1462-1464). From 1467 to 1471, Regiomontanus lived in Hungary as astrologer to Hungarian King Matyas I and Archbishop Janos Vitez. Then in Nuremberg, Germany, he opened an instrument workshop, established a printing house, and continued his planetary observations. The scholar planned to print extensive publications on classical, medieval, and modern mathematical sciences, but not all plans came to fruition.
Paolo Ricci (Italian: Paolo Ricci, Latin: Paulus Ricius, German: Paul Ritz), also known as Ritz, Riccio, or Paulus Israelita, was a humanist convert from Judaism, a writer-theologian, Kabbalist, and physician.
After his baptism in 1505 he published his first work, Sol Federis, in which he affirmed his new faith and sought through Kabbalah to refute modern Judaism. In 1506 he moved to Pavia, Italy, where he became a lecturer in philosophy and medicine at the university and met Erasmus of Rotterdam. Ricci was also a learned astrologer, a professor of Hebrew, philosophy, theology, and Kabbalah, a profound connoisseur and translator of sacred texts into Latin and Hebrew, and the author of philosophical and theological works.
Paolo Ricci was a very prolific writer. His Latin translations, especially the translation of the Kabalistic work Shaare Orach, formed the basis of the Christian Kabbalah of the early 16th century.
Celio Rodigino (Latin: Caelius Rhodiginus), real name Ludovico Ricchieri, was an Italian writer, educator and Renaissance humanist.
Rodigino studied in Ferrara and Padua, and then was professor of Greek and Latin at Rovigo. In 1515 he became chair of Greek at the University of Milan.
His principal work was Antiquarum Lectionum in sixteen books, published in Venice in 1516. In this work Rodigino collected a considerable number of short essays and notes on Latin and Greek antiquity, from literature, philology, and science to philosophy, history, anthropology, and morality, as well as reflections on ancient music. He also wrote commentaries on Virgil, Ovid, and Horace.
Werner Rolewinck (Latin: Wernerus Rolewinkius) was a German chronicler, historian, and theologian.
Werner Rolewinck was a Cartesian monk. His best known and most important work is Fasciculus temporum, a history from the creation of the world to Pope Sixtus IV. Already during his lifetime this work was republished many times in Latin, French, Dutch, and German. Drawing on major Christian historiographical sources such as Orosius and Eusebius, Fasciculus presents the history of the world in the form of a genealogy, a traditional historiographical structure dating back to late antiquity.
Another famous work by Rolewink is a description of the manners and customs of his homeland entitled De laude veteris Saxsoniæ nunc Westphaliæ dictæ.
Eucharius Rösslin the Elder or Eucharius Rößlin was a German medieval scholar, physician-midwife, and pharmacist.
In 1493 Eucharius became apothecary in Freiburg, and 13 years later was elected physician of the city of Frankfurt am Main. From there he moved to Worms, in the service of Katherine, Princess of Saxony and Duchess of Brunswick and Lüneburg. One of his duties was to oversee and supervise the city's midwives, whose ignorance led to a high infant and female mortality rate.
In order to remedy this, Eucharius wrote and published a book on midwifery called Der Rosengarten ("The Rose Garden for Pregnant Women and Midwives") in Strasbourg in 1513. It was in German and contained several engravings. The book proved very popular and soon became the standard medical textbook for midwives. For nearly two centuries it was the authoritative guide to midwifery in Europe, translated into seven languages and reprinted over a hundred times.
In 1517 Rösslin returned to work in Frankfurt and remained in that position until his death in 1526. His son, also named Eucharius Rösslin, succeeded him as city physician.
Desiderius Erasmus, also Erasmus of Rotterdam, or simply Erasmus (Latin: Desiderius Erasmus Roterodamus, Dutch: Gerrit Gerritszoon) was a Dutch humanist, philosopher, and the greatest scholar of the Northern Renaissance.
He was illegitimate and brought up under the name Gerhard Gerhards, later in Latin his name was dubbed Desiderius Erasmus. At the age of 13, the boy was sent to a monastery, where he later took the ministry. Erasmus read a lot, improving in Latin and Ancient Greek, studied oratory. A few years later he received the post of secretary to the bishop of the French city of Cambre. From 1493 to 1499 Rotterdam lived in Paris, then in London he was introduced to Thomas More, John Fisher, and John Colet.
Erasmus was constantly on the move, rarely staying in one place and traveling frequently between the Netherlands, Britain, France and Italy. In Turin he earned a doctorate in theology and was received by the Pope, then taught ancient Greek and theology at Cambridge. He corresponded with the rulers of various countries, popes and cardinals, and with statesmen, answering their questions of a scientific, political, and philosophical nature. As a true humanist, Erasmus of Rotterdam adhered to the ideas of a scientific spirit that favored research and true knowledge.
Among the merits of Rotterdamsky study of religious texts from a scientific position, critical interpretation of theology. Erasmus was able to lay the groundwork for historical-critical study of the past, especially in his studies of the Greek New Testament and the church fathers. His educational writings helped to replace the old school curriculum with a new humanistic emphasis on the classics.
In 1501, Erasmus produced a religious and ethical treatise, The Arms of the Christian Warrior, published in 1504. His work entitled "The Praise of Folly" was reprinted 40 times only during the author's lifetime, the book has been translated into all popular languages of the world. The series "Conversations in a Simple Way" (1518-1533) is among the most popular books on pedagogy. Erasmus promoted respect and care for children, opposing violence and corporal influence. He also promoted the idea that education should be compulsory for everyone.
Hartmann Schedel was a German humanist, medical scientist, historian and chronicler.
Schedel was the first to compile a world chronicle, the so-called Visual History of the Earth from the Creation of the World to the 1490s, known as Schedelsche Weltchronik (Schedel's World Chronicle). It was published in 1493 in Nuremberg. About 600 woodcuts for this book were created by the artists and engravers Michael Wolgemuth (1434-1519) and Albrecht Dürer (1471-1528). The illustrations depict biblical scenes, family trees, portraits of famous personalities, and fairy tale or legendary creatures. However, the main ones here were maps of the world, Germany and Central Europe.
Hartmann Schedel was one of the first cartographers to use machine printing. He was also a renowned collector of books, artworks and engravings by old masters.
