DR. J. ROBERT CADE!
Famous for: Inventing Gatorade. As a kidney researcher at the University of Florida, he produced the first batch of the now famous sport drink for the Gators after his research showed how players would sweat away sodium and chloride and lost plasma volume and blood volume after a three-hours-long game. His sport drink now sells worldwide and comes in more than 30 flavors (such as the delicious EXTREME Tapioca)
Cause of Death: Kidney failure, because God has a sense of humor.
