Urey, Harold Clayton (1893–1981)

Astronomy

He studied the Earth’s origin from a chemical viewpoint, deducing its constituents by supposing that final accretion occurred at about 0°C. This would have given it a primitive atmosphere of mainly water vapour, methane, ammonia, and hydrogen. In 1953 his student Stanley Lloyd Miller (1930–2007) subjected a mixture of these gases to an electrical discharge to simulate lightning, in what has come to be called the Miller–Urey experiment. After several days there had formed organic molecules important to life, in particular amino acids. Similar experiments were later carried out by others, including C. E. Sagan. Urey also studied the abundance of elements on the cosmic scale.

Chemistry

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 1934 Nobel Prize for chemistry.

Geology and Earth Sciences

of chemistry from California, Urey is best known as the discoverer of deuterium, but he also did important work on the origin and evolution of the universe and of life. In the field of Earth science he developed the use of oxygen-isotope analysis, used to indicate ancient climatic temperatures.
