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.
Before Vesalius, most information about the human body came from Galen. By dissecting human bodies, Vesalius showed that many of the things Galen wrote about were wrong. Galen was primarily misinformed about the human heart, liver and lower jaw bone. It was found that Galen's work was based on Barbary Apes, but he also dissected pigs, which led to even more inaccurate observations.
