Irving Langmuir (1881-1957)
North-American scientist, was born in Brooklyn, New York, in January 31st 1881, and died in Massachussets in August 16th 1957.
Studied in the University of Columbia and made research work in the General Electric Inc. between 1909 and 1950. Had a special interest in surface chemistry, being responsible for the explanation of surface action, that granted him the Nobel Prize of Chemistry, in 1932. Invented electric lamps in gaseous atmospheres, measured the melting point of refractory solids and discovered atomic hydrogen. As a result of his research on gaseous reaction kinetics derived the adsorption isothermic named after him. Langmuir also studied the hypothesis of producing artificial rain (1946).
