In 1933, he was offered a lifetime professorship at the Institute for Advanced Study in New Jersey when that institution's plan to appoint Hermann Weyl fell through. He remained a mathematics professor there until his death, although he had announced his intention to resign and become a professor at large at the University of California, Los Angeles. His mother, brothers and in-laws followed von Neumann to the United States in 1939. Von Neumann anglicized his first name to John, keeping the German-aristocratic surname von Neumann. His brothers changed theirs to "Neumann" and "Vonneumann". Von Neumann became a naturalized citizen of the United States in 1937, and immediately tried to become a lieutenant in the United States Army's Officers Reserve Corps. He passed the exams easily but was rejected because of his age. His prewar analysis of how France would stand up to Germany is often quoted: "Oh, France won't matter."
