Richard Phillips Feynman (1918 - 1988) American theoretical physicist, best known for his contributions to quantum electrodynamics. He won the 1965 Nobel Prize in Physics.

He was born in New York of Jewish immigrants. Barely in high school, young Richard was way ahead of his classmates, mastering calculus while they struggled with algebra. After high school he went to MIT and was appointed a Putnam Fellow upon graduation. Feynman obtained a Ph.D. from Princeton and married Arlene Greenbaum there. After working on the Manhattan Project during World War II, Feynman taught physics at Cornell and later CalTech. His most wide-ranging contributions are perhaps the Feynman diagram and the Feynman path integral, initially used in quantum mechanics, but now used widely in many other areas of mathematics and physics.

Most physicists were impressed with Feynman's ability for applied mathematics. Feynman has Erdős number 4. With Murray Gell-Mann he published an article on the theory of Fermi interaction for Phys. Rev. (2) in 1958. Gell-Mann in turn wrote an article on gauge theories with Sheldon Glashow for another physics journal, and Glashow co-authored an article on mass formulas and mass inequalities with Coleman and Daniel Kleitman. Kleitman co-authored with Erdős a paper “On coloring graphs to maximize the proportion of multicolored -edges” in the Journal of Combinatorial Theory in 1968.

Famous for making jokes and pulling pranks, Feynman often claimed he wanted to memorize to 767 decimal places (now called the Feynman point in his honor). Feynman was honored on Star Trek: The Next Generation with a shuttlecraft named after him. More recently, the United States Postal Service honored Feynman with 37-cent stamps along with fellow Manhattan Project alum John von Neumann.
