Hofstadter, Robert,1915–90, American physicist, b. New York City, Ph.D. Princeton, 1938. He taught at Princeton from 1938 to 1950 and also worked at the National Bureau of Standards during World War II. In 1950 he joined the faculty at Stanford and remained there until his retirement in 1985. Hofstadter shared the 1961 Nobel Prize in Physics with Rudolf MössbauerMössbauer, Rudolf Ludwig,

He was the first to discover that atomic particles have definite shapes and sizes, and he pinpointed the distribution of charge and magnetic moment in atomic nuclei.
Born Feb. 5, 1915, in New York. American physicist.
Hofstadter graduated from Princeton University in 1938. He then worked for the National Bureau of Standards and for the Norden Laboratory Corporation. Beginning in 1946, he was associated with Princeton University. In 1950 he began working at Stanford University, where he became a professor in 1954. In 1948, Hofstadter devised a scintillation counter that used sodium iodide activated by thallium as the scintillator and applied it to gamma spectroscopy. He then developed counters to register neutrons and X rays. He studied cosmic rays and the cascade showers generated by relativistic electrons.
Hofstadter was awarded a Nobel Prize in 1961 for his fundamental studies of electron scattering by nucleons.
