Editing Wolfgang Pauli (section)

===United States and Switzerland===
In 1940, Pauli moved to the United States, where he was employed as a professor of theoretical physics at the [[Institute for Advanced Study]]. In 1946, after the war, he became a [[Naturalization|naturalized]] U.S. citizen and returned to Zürich, where he mostly remained for the rest of his life. In 1949, he was granted Swiss citizenship.

In 1958, Pauli was awarded the [[Max Planck medal]]. The same year, he fell ill with [[pancreatic cancer]]. When his last assistant, Charles Enz, visited him at the Rotkreuz hospital in Zürich, Pauli asked him, "Did you see the room number?" It was 137. Throughout his life, Pauli had been preoccupied with the question of why the [[fine-structure constant]], a [[dimensional analysis|dimensionless]] fundamental constant, has a value nearly equal to 1/137.<ref>Sherbon, M.A. Wolfgang Pauli and the Fine-Structure Constant.
