Urey, Harold Clayton (1893–1981)
American physical chemist who was awarded the 1935 Nobel Prize in Chemistry
for his discovery of deuterium, one of
the heavy isotopes of hydrogen (1932)., which he also named. He contributed
to the growing basis for the theory of what was widely accepted as the origin
of the Earth and, in 1953, along with Stanley Miller,
carried out research into the possible make-up of Earth's primeval atmosphere
and prebiotic evolution (see Miller-Urey
During the birth of the Space Age in the 1950s, Urey was a major proponent
of solar system exploration and the search for extraterrestrial life, becoming
involved with the Apollo and Viking
missions. He also investigated organic matter in meteorites.
