Harold Urey

Harold Clayton Urey was an American physical chemist whose pioneering work on isotopes earned him the Nobel Prize in Chemistry in 1934 for the discovery of deuterium. He played a significant role in the development of the atom bomb, but may be most prominent for his contribution to theories on the development of organic life from nonliving matter.

Harold Clayton Urey was born on April 29, 1893, in Walkerton, Indiana, the son of Samuel Clayton Urey, a school teacher and a minister in the Church of the Brethren, and his wife Cora Rebecca ne Reinoehl. He had a younger brother, Clarence, and a younger sister, Martha. The family moved to Glendora, California, but moved back to Indiana to live with Coras widowed mother when Samuel became seriously ill with tuberculosis. He died when Urey was six years old.
