Stanislaw Ulam PhD is Notable.

Stanislaw Marcin Ulam was a Polish-American mathematician. He participated in America's Manhattan Project, originated the Teller–Ulam design of thermonuclear weapons, invented the Monte Carlo method of computation, and suggested nuclear pulse propulsion. In pure and applied mathematics, he proved some theorems and proposed several conjectures.[1]

In early 1943, Ulam asked von Neumann to find him a war job. In October, he received an invitation to join an unidentified project near Santa Fe, New Mexico. The letter was signed by Hans Bethe, who had been appointed as leader of the theoretical division of Los Alamos National Laboratory by Robert Oppenheimer, its scientific director. This was Ulam's introduction to the Manhattan Project, which was the US's wartime effort to create the atomic bomb.

He was born on Apr 13, 1909 in Lemberg, Galicia, Austria (now Poland)[2]. His parents were Jozef Ulam (1877-1941) and Hania Auerbach Ulam (1887-1938). He obtained his PhD in 1933 from the Lwów Polytechnic Institute in the Ukraine. He married Francoise Aron (1918-2011) in 1941, while serving as an assistant professor at the University of Wisconsin-Madison. They had previously met at Cambridge. They had one daughter, Claire, who was born in New Mexico. They lived at 1142 20th Street, Los Alamos, New Mexico after the war.[3]

Stanislaw had two siblings, Stefania Francesca (Ulam) Kruger (1912-1941) and Adam Brun Ulam (1922-2000).[4]

Stanislaw immigrated to the United States from Poland on the ship Georgic sailing from Harve on Aug 21, 1937 and arrived at the port of Ellis Island, New York, New York on Aug 28, 1937. He became a naturalized U.S. Citizen on Apr 2, 1943 in Madison, Wisconsin. He died on May 13, 1984 in Santa Fe, Santa Fe County, New Mexico, USA. He is buried at the Cimetiere de Montparnasse, City of Paris, France.[5]
