Richard Feynman

Richard Phillips Feynman (b. 1918) was an American physicist known for expanding the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and particle theory. He was also famous as an unscrupulous prankster. Feynman was one of the scientists arrested by President Joe Steele for treason in 1946. When Edward Teller offered to build an atomic bomb in three years, Steele allowed Feynman to help Teller.
