Jacques Dubois (1478-1555), also known as Jacobus Sylvius in Latin, was a French anatomist in Paris.

Late career in medicine

---

In Paris, he studied languages and mathematics; but feeling that the rewards were inadequate, Dubois switched to medicine. At the age of 51 he acquired a medical degree at the University of Montpellier, and returned to Paris to teach anatomy in the college of Trinquet. When Vidus Vidius departed for Italy, he was appointed to succeed him as professor of surgery to the Royal College. He was an admirer of Galen, and interpreted the anatomical and physiological writings of that author in preference to giving demonstrations from the subject.

Frustrations of his pupils

---

Vesalius, who was his (frustrated) pupil, states that his manner of teaching was calculated neither to advance the science nor to rectify the mistakes of his predecessors. A human body was never seen in Dubois' anatomical theatre. The carcases of dogs and other animals were the materials from which he taught. It was so difficult to obtain human bones, that Vesalius and his fellow-students had to collect them themselves from the Cimetière des Innocents and other cemeteries. Without these, they must have committed numerous errors in acquiring the first principles.

Though Jean Riolan (1580-1657) contradicted these comments and accused Vesalius of ungratitude, it is certain that the frustrations that Vesalius experienced were the basis for which he later traveled to Padua and became a famous anatomist himself. Only in Italy were the opportunities of inspecting the human body frequent enough as to facilitate the study of the science. This period was a time of fierce debate between Galenists and the new body of thought on anatomy. The conservative Riolan attacked William Harvey with equal fervour.

Legacy

Though the first acknowledged professor of anatomy to the University of Paris, Dubois appears in history as one who lived without true honour and died without just celebrity. He must not be confused with Franciscus Sylvius (de le Boe), the Dutch physician.
