Louis Bolk, Dutch anatomist and biologist (died 1930)

Louis Bolk
Lodewijk 'Louis' Bolk was a Dutch anatomist who created the fetalization theory about the human body. It states that when a human being is born, it is still a fetus, as can be seen by its (proportionally) big head, lack of coordination, and helplessness. Furthermore, this "prematuration" is specifically human.
