#American #scientist awarded the #NobelPrize for Chemistry in 1934 for his discovery of #deuterium, the heavy form of hydrogen (1932).

He was active in the development of the #AtomicBomb.

He contributed to the growing basis for the theory of what was widely accepted as the #origin of the #Earth and other #planets.

In 1953, Stanley L. Miller and Urey simulated the effect of lightning in the prebiotic #atmosphere of Earth with an #electrical discharge in a mixture of hydrogen, methane, ammonia, and water. This produced a rich mixture of #aldehydes and carboxylic and #aminoacids (as found in proteins, adenine and other nucleic acid bases).

Urey calculated the temperature of ancient oceans from the amount of certain isotopes in fossil shells.
