10. Charles Darwin

It may come as no surprise that naturalist Charles Darwin took a uniquely scientific approach to eating. He led the Glutton Club during his years as a student at Cambridge University. The Glutton Club's mission was to procure and eat the strangest and rarest species known to gourmets.

Darwin ate hawk, bittern (a waterfowl) and, once, even an old brown owl. He tried armadillo and unknown large rodents. And, by the way, he said that armadillo tasted like duck.

Darwin's wife enjoyed cooking for her husband, and today you can even buy a book of her recipes, culled from her personal notes.
