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,

 for his pioneering work in uncovering the structure and composition of neutrons and protons, the particles that make up the nuclei of atoms. 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.

Hofstadter, Robert

 

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.

Hofstadter, Robert

(1915–90) physicist; born in New York City. He performed research at Princeton (1939–40), then taught at the University of Pennsylvania (1940–41) and City College, N.Y. (1941–42). After working for the National Bureau of Standards (1942–43) and Norden Laboratories Corporation (1943–46), he returned to teaching at Princeton (1946–50), then Stanford (1950–80). He shared the 1961 Nobel Prize in physics for his pioneering research on the structure of protons and neutrons.
