Anatomy
Andreas Vesalius (1514–1564) (Latinized from Andries van Wezel), professor of anatomy at the University of Padua, is considered the founder of modern human anatomy. Originally from Brabant, Vesalius published the influential book "De humani corporis fabrica" ("the structure of the human body"), a large format book in seven volumes, in 1543. The accurate and intricately detailed illustrations, often in allegorical poses against Italianate landscapes, are thought to have been made by the artist Jan van Calcar, a pupil of Titian.
Alessandra Giliani
Alessandra Giliani (1307-1326) was thought to be an Italian natural historian, best known as the first woman to be recorded in historical documents as practicing anatomy and pathology. However, the historical evidence for her existence is limited. Some scholars consider her to be a fiction invented by  Alessandro Machiavelli (1693-1766) . whilst others hold that the participation of a woman in anatomy at that time was so shocking that she has been edited out of history .
Giliani is believed to have been born in 1307, in San Giovanni in Persiceto, in the Italian province of Emilia-Romagna. The chronicle of her life holds that she died in 1326, possibly from a septic wound, at the age of 19. Celebrated as the first female anatomist of the Western World, she is reputed to have been a brilliant prosector (preparer of corpses for anatomical dissection). She is said to have worked as the surgical assistant to Mondino de' Liuzzi (d. 1326), a world-renowned professor at the medical school of the University of Bologna. (Credited with being the father of modern anatomy, de' Liuzzi published a seminal text on the subject in 1316.)
