[bahr-deen]
Bardeen, John, 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 Schrieffer for development of a theory of superconductivity, becoming the first person to win a Nobel Prize twice in the same field.

Bardeen.

(born May 23, 1908, Madison, Wis., U.S.—died Jan. 30, 1991, Boston, Mass.) U.S. physicist. He earned a Ph.D. in mathematical physics from Princeton University. He worked for the U.S. Naval Ordnance Laboratory during World War II, after which he worked for Bell Telephone Laboratories. His work there led to his sharing a 1956 Nobel Prize with William B. Shockley and Walter H. Brattain for the invention of the transistor. In 1972 he again shared a Nobel Prize, this time with Leon Cooper and J. Robert Schrieffer for developing the theory of superconductivity (1957); this theory (called the BCS theory, for Bardeen-Cooper-Schrieffer) is the basis for all later theoretical work in superconductivity. Bardeen was also the author of a theory explaining certain properties of semiconductors.
