Andreas Vesalius (31 December 1514 – 15 October 1564) was a Flemish anatomist, physician, and author. He wrote one of the most influential books on human anatomy, "De humani corporis fabrica" ("On the Fabric of the Human Body"). Vesalius is often called the founder of modern human anatomy. Vesalius is the Latinized form of Andries van Wesel. He is sometimes also called Andreas Vesal, André Vesalio and Andre Vesale.
