A graduate of U Chicago, where he studied experimental physics, gaining his PhD in 1941, Metropolis was one of the original recruits to the Manhattan project at the Los Alamos Laboratory. His career alternated between there and U Chicago. To statisticians he is best known for his work on Monte Carlo methods. He coined this term, and he was also responsible for naming the elements astatine and technetium at the time of their discovery.
