On June 15, 1667, French physician and scientist, Jean-Baptiste Denys, successfully administered the first documented case of blood transfusion into a human. He transfused twelve ounces of sheep’s blood into a 15-year old peasant boy. To make sure there was space for the blood, Denys had bled the boy 20 times with leeches. The lad survived. When asked why the boy had volunteered for this experiment, Jean-Baptiste Denys replied, “Volunteered? He’s a peasant. He does what he’s told.” Jean-Baptiste Denys, a curious man and scientist, but also a dick of a person. The peasant boy? He grew up with little to no harm. He did develop a fondness for sheep, but he was part Welsh.
