Langmuir, Irving (1881-1957), químico estadounidense conocido por su trabajo en distintos campos de la química. Langmuir nació en Brooklyn (Nueva York) y estudió en las universidades de Columbia y Gotinga. Desde 1932 hasta su jubilación en 1950, fue director adjunto del laboratorio de investigación de la General Electric Company. Trabajó en el desarrollo de las lámparas de tungsteno, en el aparato de descarga de electrones, en las bombas de vacío y en la soldadura de hidrógeno atómico. Langmuir y su colega estadounidense Gilbert Lewis desarrollaron una teoría de la interacción química y la valencia basada en la estructura del átomo, conocida como teoría de Langmuir-Lewis. La investigación de Langmuir en la física de las nubes le condujo a la estimulación artificial de la lluvia. Por su trabajo en películas monomoleculares y en química de superficies, fue galardonado en 1932 con el Premio Nobel de Química.

Langmuir, Irving (b. Jan. 31, 1881, Brooklyn, N.Y., U.S.d. Aug. 16, 1957, Falmouth, Mass.), American physical chemist whose studies of molecular films on solid and liquid surfaces opened new fields in colloid research and biochemistry and won him the Nobel Prize in Chemistry for 1932. Investigating electrical discharges in gases, electron emission, and the high-temperature surface chemistry of tungsten, Langmuir greatly extended the life of the tungsten-filament light bulb. He also developed a vacuum pump, high-vacuum tubes used in radio broadcasting, and an atomic hydrogen blowtorch capable of producing temperatures greater than 3,000 C (6,000 F). Working independently of the American atomic chemist Gilbert N. Lewis, Langmuir formulated theories of atomic structure and chemical bond formation and introduced the term covalence. In 1946 he and his associates began to explore the possibility of inducing rainfall by seeding clouds with silver iodide and solidified carbon dioxide.

37. Langmuir, Irving langmuir, irving (18811957) langmuir was born in New York and studied thereat Columbia University and in Germany at Göttingen. http://www.cartage.org.lb/en/themes/Biographies/MainBiographies/L/Langmuir/1.htm

Langmuir, Irving US scientist who invented the mercury vapour pump for producing a high vacuum, and the atomic hydrogen welding process; he was also a pioneer of the thermionic valve. In 1932 he was awarded a Nobel prize for his work on surface chemistry. Langmuir's research on electric discharges in gases at very low pressures led to the discovery of the space-charge effect: the electron current between electrodes of any shape in vacuum is proportional to the 3/2 power of the potential difference between the electrodes. He also studied the mechanical and electrical properties of tungsten lamp filaments. Langmuir's introduction of nitrogen into light bulbs prevented them from blackening on the inside but increased heat loss, which was overcome by coiling the tungsten filament. Langmuir was the first to use the terms 'electrovalency' (for ionic bonds between metals and nonmetals) and 'covalency' (for shared-electron bonds between nonmetals). During the 1920s, Langmuir became particularly interested in the properties of liquid surfaces. He went on to propose his general adsorption theory for the effect of a solid surface during a chemical reaction.

A D V E N T U R E S in C Y B E R S O U N D Irving Langmuir : 1881 - 1957 Dr. Irving Langmuir, one of the twentieth century's outstanding chemists, was born in Brooklyn, NY where his father was employed as an insurance executive. Educated in the public schools of New York and Paris, France, he earned a B.S. degree from the Columbia University Schools of Mines and a Ph.D. in chemistry from the University of Gottingen Germany, where he studied under Nobel Laureate Walter Nernst. His first professional position was an instructor of chemistry at Stevens Institute, Hoboken, NJ from 1906 to 1909. He moved on to the General Electric Research Laboratory, Schenectady, NY, in 1909. There he spent the remainder of a prolific career that was to include more than 200 scientific publications, 63 patents, and the recipient of numerous honors, including the 1932 Nobel Prize for Chemistry. Dr. Langmuir's initial researches at the General Electric involved low-pressure chemical reactions and the study of the emission of electrons by hot filaments in a vacuum. This work led directly to two major inventions: the high vacuum electron tube (1912) and the gas-filled incandescent lamp (1913), which remains the most important type of indoor lighting in sizes of 40 watts and up. In addition, these early researches led Dr. Langmuir to formulate his theory of absorption, describing the formation of single layers of molecules on surfaces in terms of chemical bonding forces. This work forms the foundation of modern work on surface chemistry, with major implications for such fields as catalysis, and the orientation of molecules at liquid or solid surfaces. It is the basis for the Nobel Award that he received.
