Inspirational Quotes by Harold Urey (American Chemist)

Harold Urey (1893–1981,) fully Harold Clayton Urey, was an American chemist. This winner of the 1934 Nobel Prize in Chemistry discovered deuterium and pioneered the use of isotope labeling.

Born in Walkerton, Indiana, Urey taught in rural schools and then studied at Montana State University and the University of California at Berkeley. In 1923–24, he worked with Niels Bohr in Copenhagen. Subsequently, he taught at Johns Hopkins University, Columbia University, University of Chicago, and the University of California-La Jolla.

Urey’s earliest research was on atomic and molecular spectra and structure, but he is chiefly remembered for his discovery in 1932 of heavy hydrogen (deuterium.) Later he made many studies of the separation of isotopes and isotopic exchange reactions. During World War II, he was prominent in separating uranium-235 for the atomic bomb as part of the Manhattan Project. He later advocated an international ban on nuclear weapons.

After the war, Urey researched geochemistry and cosmochemistry, making fundamental contributions to a widely accepted theory of the origin of the Earth and other planets. He wrote The Planets (1952) and Some Cosmochemical Problems (1961.)

Above all, I regret that scientific experiments—some of them mine—should have produced such a terrible weapon as the hydrogen bomb. Regret, with all my soul, but not guilt.
