Andreas Vesalius was a Belgian anatomist born in 1514. He worked with cadavers from graveyards or gallows to correct errors in the study of anatomy and created many artistic, yet accurate renderings of the human form. His work was considered to be groundbreaking as he corrected many of Galen’s errors and followed in the footsteps of Leonardo da Vinci who also performed human dissections. Three hundred years later Darwin used Vesalius’s anatomical knowledge to build the theory of evolution.
