Harold Clayton Urey 1934 Nobel Laureate in Chemistry Harold Clayton Urey (1893-1981) Selected works Biography: Urey was a son of small town, pre-industrial America; he once told colleagues that the first time he saw an automobile was at age 17 in rural Montana. After graduating from high school, he taught in small country schools for three years, before working his way through the University of Montana. He studied thermodynamics as a PhD student with G. N. Lewis at Berkeley, and then spent a year studying quantum theory in Europe with Niels Bohr, returning to the US in 1924. He apparently was the first Berkeley educated PhD chemist to win a Nobel Prize. He joined the Columbia Chemistry Faculty at age 36 in 1929, after 5 years at Johns Hopkins where he collaborated with F. O. Rice among others. He was a pioneer in application of quantum mechanics to molecules, and wrote Atoms, Molecules, and Quanta in 1930 with A. E. Ruark. At Columbia he was founding editor of the

Chemist Faculty 1929-45 ScD 1946 (hon.) Harold C. Urey received the Nobel Prize for Chemistry in 1934 for his discovery of deuterium, an essential component of thermonuclear weaponry and nuclear-powered reactors. In a long and varied career, he contributed to significant advances in the fields of physical chemistry and geochemistry, and is credited with being the founder of "cosmochemistry," the term he coined to describe the field of modern lunar science, for his speculations and deductions about the moon's geology. He conducted fundamental work on the structure of atoms and molecules, the thermodynamic properties of gases, and the separation of isotopes. In the late 1940s, he invented the methods now universally used to analyze climate warming and cooling cycles. In 1953, he and PhD student Stanley Miller performed an experiment in which they were able to form four amino acids, the basic building blocks of contemporary life forms on Earth. Their success transformed research on the origins of life. Urey came to Columbia in 1929 after five years at Johns Hopkins, preceded by a year studying quantum theory with Niels Bohr in Copenhagen. While on the Columbia faculty, Urey co-wrote

var loaded_bol = false; Chemist ScD 1946 (hon.) Director of War Research, Manhattan Project Professor's 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 isotopes 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. He is the author of the books Atoms, Molecules and Quanta

Harold Clayton Urey Harold Clayton Urey American scientist awarded the Nobel Prize for Chemistry in 1934 for his discovery of the heavy form of hydrogen known as deuterium. He was a key figure in the development of the atomic bomb and made fundamental contributions to a widely accepted theory of the origin of the Earth and other planets. Urey received a B.S. degree from Montana State University (now the University of Montana), Missoula, in 1917. After teaching there for two years, he earned a Ph.D. in chemistry (1923) from the University of California at Berkeley. While he was doing research in Copenhagen (1923-24), Urey took part in Niels Bohr's basic research on the theory of atomic structure. He taught at Johns Hopkins University, Baltimore (1924-29), and at Columbia University (1929-45); was professor of chemistry at the Institute for Nuclear Studies (1945-52) and Ryerson professor of chemistry (1952-58) at the University of Chicago; and served as professor-at-large (1958-70) and as professor emeritus of chemistry (1970-81) at the University of California at San Diego. Urey's deuterium research began in the 1920s. By distilling a sample of liquid hydrogen, he concentrated its deuterium form, demonstrating its presence by light-emission studies. In 1931 he and his associates announced their discovery of heavy water, composed of an atom of oxygen and two atoms of deuterium. He also examined the chemical properties and separation of radioactive isotopes of carbon, oxygen, nitrogen, and sulfur.
