Urey, Harold Clayton (1893-1981) US chemist, Nobel Prize in 1934 for the discovery of deuterium and known for the idea of inorganic life formation (MiUer-Urey experiment)... 

Urey, Harold Clayton (1894-1981) US physical chemist, who became a professor at the University of California in 1958. His best-known work was the discovery of deuterium (heavy hydrogen) in 1932, for which he was awarded the 1939 Nobel Prize for physics. 

Urey, Harold Clayton (1893-1981) American chemist who discovered deuterium (heavy hydrogen), the isotope of hydrogen that has a neutron and a proton in the nucleus and is thus twice the weight of common hydrogen, which has only a proton. Urey also worked with Stanley Miller to simulate a primitive atmosphere, thought to be similar to Earth s early atmosphere. Urey was awarded the Nobel Prize in chemistry in 1934. 

Harold Clayton Urey, 1893-. Professor of chemistry at the Institute for Nuclear Studies at the University of Chicago and at the University of California. In 1931 Dr. Urey and his collaborators discovered deuterium, the heavy isotope of hydrogen. Pie has carried out notable researches on the entropy of gases and on the properties and separation of isotopes and has studied the chemical evidence of the earth s origin. 

Urey, Harold (1893-1981) American Physical chemist, geophysicist Harold Clayton Urey was born in Walkerton, Indiana, on April 29, 1893, to Rev. Samuel Clayton Urey and Cora Rebecca Reinsehl. His early education was in rural schools, and he graduated from high school in 1911 and taught for three years in country schools.

During the 1920s, Lord Ernest Rutherford had suggested that a heavy hydrogen isotope could exist, and there was some evidence for this idea. The American scientist Harold Clayton Urey found that if liquid hydrogen was fractionally distilled, he could obtain a fraction richer in the heavier isotope, and when he examined the atomic spectrum of these samples, he detected lines that were not due to ordinary hydrogen, thus were caused by the presence of small amounts of deuterium (D).
