Irving Langmuir(/ˈlæŋmjʊər/;January 31, 1881 – August 16, 1957) was an Americanchemist,physicist, andmetallurgical engineer. He was awarded theNobel Prize in Chemistryin 1932 for his work insurface chemistry. Langmuir's most famous publication is the 1919 article "The Arrangement of Electrons in Atoms and Molecules" in which, building onGilbert N. Lewis'scubical atomtheory andWalther Kossel's chemical bonding theory, he outlined his "concentric theory of atomic structure".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.While atGeneral Electricfrom 1909 to 1950, Langmuir advanced several fields ofphysicsandchemistry, inventing the gas-filledincandescent lampand thehydrogen welding technique. TheLangmuir Laboratory for Atmospheric ResearchnearSocorro, New Mexico, was named in his honor, as was theAmerican Chemical Societyjournal forsurface sciencecalledLangmuir.
