Harold Clayton Urey Papers
MSS 0044 Mandeville Special Collections Library Geisel Library University of California, San Diego Papers of Harold Clayton Urey, Nobel Prize-winning chemist who contributed to significant advances in the fields of physical chemistry, geochemistry, lunar science, and astrochemistry. He received the Nobel Prize for Chemistry in 1934 for his discovery of deuterium, and made key scientific contributions to the development of the atomic bomb during World War II. He conducted fundamental work on the structure of atoms and molecules, the thermodynamic properties of gases, the separation of isotopes, and the chemical problems involved in the origin of the earth, the moon, and the solar system. He was also an advocate of nuclear arms control, working actively with other scientists to promote global cooperation and to prevent nuclear proliferation and conflict. Among Urey's teaching positions were posts at Montana State University, Johns Hopkins University, Columbia University, the University of Chicago, and the University of California, San Diego. The papers span the years 1929 to 1981 and are organized into ten series: 1) BIOGRAPHICAL MATERIALS, 2) GENERAL CORRESPONDENCE, 3) SUBJECT FILES, 4) WRITINGS, 5) WRITINGS OF OTHERS, 6) PERSONAL EPHEMERA, 7) PHOTOGRAPHS, 8) AWARDS, 9) LUNAR ORBITER PHOTOS AND CHARTS, and 10) ORIGINALS OF PRESERVATION PHOTOCOPIES.

Harold Clayton Urey Papers
Background
Harold Clayton Urey was a scientist of considerable scope whose discovery of deuterium helped him win the Nobel Prize for Chemistry in 1934. Urey also made fundamental contributions to the production of the atomic bomb through his development of the isotope separation processes for the Manhattan Project. In the period following World War II, Urey played an active part in advocating nuclear arms control, in promoting space exploration and in the development of the newly created campus of the University of California, San Diego. Born in Walkerton, Indiana, on April 29, 1893, Harold Urey was the son of Samuel Clayton and Cora Rebecca (Reinohl) Urey. His early schooling took place in rural Indiana. After graduating from high school he taught in country schools in Indiana and Montana for three years. In 1914 he entered Montana State University where he majored in zoology and minored in chemistry. He received a Bachelor of Science degree in 1917 and worked as an industrial chemist in Philadelphia until the end of World War I. He then returned to Montana as an instructor in the department of chemistry, where he remained for two years before pursuing a doctorate at the University of California, Berkeley. At Berkeley Urey studied thermodynamics and worked with Gilbert N. Lewis. Urey's doctoral research dealt with the rotational contributions to the heat capacities and entropies of gases, a subject not well understood at the time. He was able to form calculations which led directly to the present methods of calculating thermodynamic functions from spectroscopic data.

BIOGRAPHICAL MEMOIRS National Academy of Sciences
Harold Clayton Urey
By James R. Arnold, Jacob Bigeleisen, and Clyde A. Hutchison Jr.
HAROLD UREY WAS A scientist whose interests, accomplishments, and influence spanned the disciplines of chemistry, astronomy, astrophysics, geology, geophysics, and biology. Although he was meticulous in his attention to detail, his sights were always on broad questions at the forefront of knowledge. His unusual powers of concentration and capacity for hard work accounted for much of his success in exploring and opening up major new fields of research, including his discovery of deuterium and work on isotope chemistry, isotope separation, isotope geology, and cosmochemistry. Urey's approach to a new area began with his becoming thoroughly familiar with what was known about the subject of his curiosity and then the formulation of a theory to explain a large amount of uncorrelated material, which was then followed by carefully planned experiments. The latter frequently involved the design of new experimental equipment beyond the state of the art. As a graduate student in physical chemistry in the early 1920s, Urey realized that future progress in that discipline would require a knowledge of the quantum theory of atomic and molecular systems, which was undergoing a revolution in Europe. He supplemented his command of mathematics and physics by formal coursework prior to going to the Bohr Institute in Copenhagen in 1923. His exposure there led to his formulation of the concept of the electron spin concurrent with but less complete than the Goudsmit-Uhlenbeck discovery. After completion of his text with Arthur Ruark

Columbia Chemistry Professor Harold Urey experimentally proved the existence of deuterium in 1931. Urey won the 1934 Nobel Prize in Chemistry, and the American Chemical Society Gibbs Medal, for this discovery. Early that year Urey had conceived and worked out a method for concentration of a possible heavy hydrogen isotope by distillation of liquid hydrogen. The fractional distillation was done in collaboration with Brickwedde at NBS in Washington DC; 5 liters of liquid hydrogen was distilled down to 1 cc. Urey detected deuterium by its predicted spectrum in a discharge through the gas of this concentrated residue. High resolution atomic hydrogen spectra in the visible were obtained on a new 21 ft. spectrograph in the basement of Pupin Hall. The critical data clinching the discovery were taken by Urey and his assistant George Murphy on Thanksgiving Day 1931. Urey shared his Nobel Prize money with his collaborators, giving one quarter each to Murphy and Brickwedde. 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

Urey, Harold Clayton
US chemist. In 1932 he isolated heavy water and discovered deuterium, for which he was awarded the 1934 Nobel Prize for Chemistry.
During World War II he was a member of the Manhattan Project, which produced the atomic bomb, and after the war he worked on tritium (another isotope of hydrogen, of mass 3) for use in the hydrogen bomb, but later he advocated nuclear disarmament and world government.
Urey was born in Indiana and educated at Montana State University. He became professor of chemistry at Columbia 1934, and was at Chicago 1945-58.
After deuterium, Urey went on to isolate heavy isotopes of carbon, nitrogen, oxygen, and sulphur. His group provided the basic information for the separation of the fissionable isotope uranium-235 from the much more common uranium-238.
Urey also developed theories about the formation of the Earth.
He thought that the Earth had not been molten at the time when its materials accumulated. In 1952, he suggested that molecules found in its primitive atmosphere could have united spontaneously to give rise to life. The Moon, he believed, had a separate origin from the Earth.

Urey, Harold Clayton Né le 29 avril 1893 à Walkerton, petit village de l'Indiana aux Etats-Unis, dans une famille d'enseignants, Harold Clayton Urey est élevé par sa mère, très t6t veuve, et commence ses études dans des écoles provinciales plut6t médiocres, exerçant ensuite pendant trois ans comme instituteur. Puis il s'inscrit à l'Université de l'Indiana et à l'Université d'Etat du Montana. Etudiant en sciences, il marque une nette préférence pour la zoologie. Appelé à servir dans un laboratoire militaire durant la Première Guerre mondiale, il se découvre une passion pour la chimie, et comme il l'écrira plus tard, fait "une expérience fort heureuse car elle [l']a convaincu qu'[il n'était] pas fait pour la chimie industrielle; [il préférait] la recherche pure."
Après la guerre, il est nommé moniteur de chimie à l'Université du Montana, et en 1921 commence à préparer une thèse à l'Université de Califomie. Sous la direction du célèbre thermodynamicien Gilbert Newton Lewis, il étudie l'entropie des gaz diatomiques, qu'il calcule à partir des spectres moléculaires. Ayant soutenu sa thèse en 1923, Urey se toume alors vers l'étude de la structure atomique et s'en va passer l'année 1923-1924 à l'Institut de Physique théorique de Copenhague, où Nils Bohr l'encourage à poursuivre dans cette voie.
De retour aux Etats-Unis, il est chargé de recherches à l'Université Johns Hopkins, puis, de 1929 à 1945, il travaille à l'Université Columbia de New York, où il se consacre à l'étude des isotopes, publiant en 1930 un ouvrage, Les Atomes, les Molécules et les Quanta, en collaboration avec Arthur E. Ruark . De 1945 à 1958, il exerce à l'Université de Chicago, puis il est nommé professeur à l'Université de Califomie (à La Jolla), où il reste jusqu'à sa retraite.
