The Energy Library Site Map Dictionary Timeline ... Energy Places Enter your keywords: Langmuir, Irving Irving Langmuir was an American physicist and chemist who developed the modern surface chemistry and the theory of absorption catalysis. He discovered monomolecular films with specific molecular orientation at surfaces and promoted understanding of plasmas, heat transfer, and thermionic phenomena. Langmuir also invented a high-vacuum electron tube, gas-filled incandescent lamp. He received the 1932 Nobel Prize in chemistry for his discoveries and investigations in surface chemistry, the first non-academic chemist to receive the Prize. His most noted publication was the famous 1919 article " The Arrangement of Electrons in Atoms and Molecules " in which he outlined his "concentric theory of atomic structure,” building on Gilbert N. Lewis’s cubical atom theory and Walther Kossel’s chemical bonding theory. Langmuir was one of the first scientists to work with plasmas and was the first to call these ionized gases by that name, because they reminded him of blood plasma. Langmuir and Tonks discovered electron density waves in plasmas that are now known as Langmuir waves. He also introduced the concept of electron temperature and in 1924 invented the diagnostic method for measuring both temperature and density with an electrostatic probe, now called a Langmuir probe and commonly used in plasma physics. He also discovered atomic hydrogen, which he put to use by inventing the atomic hydrogen welding process; the first plasma weld ever made. Plasma welding has since been developed into gas tungsten arc welding.

Britannica CD Index Articles Dictionary Help 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 U.S. 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.

Langmuir became embroiled in a priority dispute with Lewis over this work; Langmuir's presentation skills were largely responsible for the popularization of the theory, although the credit for the theory itself belongs mostly to Lewis.

Irving Langmuir B iography - Nobel Prize Winner (1932) Irving Langmuir (January 31, 1881 in Brooklyn, New York - August 16, 1957 in Woods Hole, Massachusetts) was an American chemist and physicist. While at G.E., from 1909-1950, Langmuir advanced several basic fields of physics and chemistry, invented the gas filled incandescent lamp, the hydrogen welding technique, and was awarded the 1932 Nobel Prize for Chemistry for his work in surface chemistry. Early years Irving Langmuir was born in Brooklyn, New York on January 31, 1881. He was the third child (out of four) of Charles Langmuir and Sadie, née Comings. During his childhood, Langmuir's parents actively encouraged him to carefully observe nature and to keep a detailed record of his various observations. When Irving was eleven, it was discovered that he had rather poor eyesight. When this problem was corrected, details and observations that had previously eluded him were revealed. Because of this, his interest in nature and the various complications of nature was heightened. During his childhood, Langmuir was greatly influenced by his older brother Arthur Langmuir. Arthur was a research chemist who also encouraged Irving to be curious about nature and how things work. Arthur helped Irving set up his first chemistry lab in the corner of his bedroom and he was always there to answer the myriad of questions that Irving would pose to him (which most of the time were on rather trivial matters). Langmuir married Marion Mersereau in 1912. They had a son, Kenneth, and a daughter, Barbara.
