Stanisław Ulam (1909–1984)
Born 1909 CE, died 1984 CE.
Stanisław Marcin Ulam (Polish: [sta'ɲiswaf 'mart͡ɕin 'ulam]; 13 April 1909 – 13 May 1984) was a Polish-American mathematician who made important contributions in advancing the understanding of nuclear physics and computer science. He participated in the Manhattan Project, originated the Teller–Ulam design of thermonuclear weapons, recognised the concept of the cellular automaton, invented the Monte Carlo method of computation, and championed nuclear pulse propulsion. In pure and applied mathematics, he proved a number of theorems and proposed several conjectures. Born into a wealthy Polish Jewish family in Lemberg, Austria-Hungary, Ulam studied mathematics at the Lwów Polytechnic Institute, where he earned his PhD in 1933 under the supervision of Kazimierz Kuratowski and Włodzimierz Stożek. In 1935, John von Neumann, whom Ulam had met in Warsaw, invited him to come to the Institute for Advanced Study in Princeton, New Jersey, for a few months. From 1936 to 1939, he spent summers in Poland and academic years at Harvard University in Cambridge, Massachusetts, where he worked to establish important results regarding ergodic theory.
