Langmuir, Irving (sh)




born Jan. 31, 1881, Brooklyn, N.Y., N.Y., U.S.
died Aug. 16, 1957, Falmouth, Mass.

U.S. physical chemist.

He received a Ph.D. from the University of G?ttingen, Ger. As a researcher for General Electric (1909-50), he investigated electrical discharges in gases, electron emission, and the high-temperature surface chemistry of tungsten, making possible a great extension in the life of tungsten-filament lightbulbs. He developed a vacuum pump and the high-vacuum tubes used in radio broadcasting. He formulated theories of atomic structure and chemical bond formation, introducing the term covalence. He received a Nobel Prize in 1932.
