    Harold Clayton Urey ForMemRS (/ ˈ j ʊər i / YOOR-ee; April 29, 1893 – January 5, 1981) was an American physical chemist whose pioneering work on isotopes earned him the Nobel Prize in Chemistry in 1934 for the discovery of deuterium.

  3. He was editor of the Journal of Chemical Physics during 1933-1940 and he has written numerous papers on the structure of atoms and molecules, the discovery of heavy hydrogen and its properties, separation of isotopes, measurement of paleotemperatures and the origin of planets.

  4. Harold Urey wondered if the smallest atom, hydrogen, had different isotopes, and he calculated how they ought to be constituted if that were the case. By distilling liquid hydrogen, a hydrogen isotope was extracted in 1932 that was twice as heavy as regular hydrogen. It was called deuterium.
