Richard Feynman (May 11, 1918 – February 15, 1988) was an American theoretical physicist who received the Nobel Prize in Physics in 1965 for his contributions to quantum electrodynamics, jointly with Julian Schwinger and Sin’ichirō Tomonaga. He developed the path integral formulation of quantum mechanics, and studied superfluidity in supercooled liquid helium. During World War II he assisted in the development of the atomic bomb, and in the 1980s he was a member of the Rogers Commission that investigated the Space Shuttle Challenger disaster. He was a pioneer in the field of quantum computing, and introduced the concept of nanotechnology. Through his lectures and books, including the semi-autobiographical Surely You’re Joking, Mr. Feynman! and What Do You Care What Other People Think?, he was an avid popularizer of physics. In a 1999 poll of leading physicists, he was ranked as one of the ten greatest physicists of all time.
