1. Human Anatomy (1538) Andreas Vesalius dissects human corpses, revealing detailed information about human anatomy and correcting earlier views. Vesalius believes that understanding anatomy is crucial to performing surgery, so he dissects human corpses himself (unusual for the time). His anatomical charts detailing the blood and nervous systems, produced as a reference aid for his students, are copied so often that he is forced to publish them to protect their accuracy. In 1543 he publishes De Humani Corporis Fabrica, transforming the subject of anatomy.

But as is typical with the Science Guy, it's not all science and no play.
