Harold C. Urey From Wikipedia, the free encyclopedia. (Redirected from Harold Clayton Urey Harold Clayton Urey April 29 January 5 ) was a chemist whose pioneering work on isotopes earned him the Nobel Prize for Chemistry in and later led him to theories of planetary evolution. Urey was born in Walkerton, Indiana . After briefly teaching in rural schools, Urey earned a degree in zoology from the University of Montana and a Ph.D. in chemistry , studying thermodynamics under G.N. Lewis at the University of California, Berkeley At Berkeley , Urey was influence by the work of physicist Raymond T. Birge and soon joined Niels Bohr in Copenhagen to work on atomic structure at the Institute for Theoretical Physics . On his return to the US in he taught at Johns Hopkins University , and then at Columbia where he assembled a team of associates that included Rudolph Schoenheimer David Rittenberg and T. I. Taylor During this time, Urey isolated deuterium by repeatedly distilling a sample of liquid hydrogen . In , he and his associates went on to demonstrate the existence of heavy water . Urey was awarded the Nobel Prize in chemistry in for this work.

Nobel Prize Winning Chemists Harold Clayton Urey The Nobel Prize In Chemistry 1934 Harold Clayton Urey was born in Walkerton, Indiana, on April 29, 1893, as the son of the Rev. Samuel Clayton Urey and Cora Rebecca Reinoehl. His early education in rural schools led to his graduation from high school in 1911 after which he taught for three years in country schools. In 1914 he entered the University of Montana and received his Bachelor of Science degree in Zoology in 1917. He spent two years as a research chemist in industry before returning to Montana as an instructor in chemistry. Professor Urey's early researches concerned the entropy of diatomic gases and problems of atomic structure, absorption spectra and the structure of molecules. In 1931 he devised a method for the concentration of any possible heavy hydrogen isotopes by the fractional distillation of liquid hydrogen: this led to the discovery of deuterium. Together with the late Dr. E. W. Washburn, he evolved the electrolytic method for the separation of hydrogen isotopes and he carried out thorough investigations of their properties, in particular the vapor pressure of hydrogen and deuterium, and the equilibrium constants of exchange reactions. He later worked on the separation of uranium isotope and, more recently, he has been concerned with the measurement of paleotemperatures, investigations into the origin of the planets, and the chemical problems of the origin of the earth.
