John Bardeen

John Bardeen , 1908-91, American physicist, b. Madison, Wis., grad. Univ. of Wisconsin (B.S. 1928, M.S. 1929), Ph.D. Princeton, 1936. He was a research physicist at the Bell Telephone Laboratories from 1945 to 1951. In 1951 he became professor of electrical engineering and physics at the Univ. of Illinois. He is known for his studies of semiconductors and other aspects of solid state physics. He shared with Walter H. Brattain and William Shockley the 1956 Nobel Prize in Physics for their work in developing the transistor. He also shared the 1972 Nobel Prize in Physics with Leon Cooper and John Schreiffer for development of a theory of superconductivity , becoming the first person to win a Nobel Prize twice in the same field.

Bardeen, John (1908–91) US physicist known for his research into semiconductors. He worked (1945–51) with the Bell Telephone Laboratories, and was professor of physics (1951–75) at the University of Illinois. He was the first person to win the Nobel Prize twice in the same field, physics: in 1956 he shared it with William Shockley and Walter Brattain, for their invention of the transistor, and in 1972 with Leon Cooper and John Schrieffer, for the theory of superconductivity.
