Otto Warburg is probably one of the most important scientists of the 20^th century and one those outside of cancer research have never heard of.

His discovery of how cancer cells devour glucose or blood sugar at a rate of 10 times that of healthy cells in the body became known as the Warburg effect.

Otto Warburg was a gay Jewish man who survived Nazi death camps in Germany because Hitler and the Nazis feared cancer and thought Warburg may be able to cure cancer. A new book examines Warburg’s fascinating life and how his theories on cancer may be coming back into vogue.

The book is called Ravenous: Otto Warburg, the Nazis and the Search for the Cancer-Diet Connection. The book’s author Sam Apple, who hails from the Philadelphia suburbs is on Tuesday’s Smart Talk.
