“American theoretical physical chemist who became the only person to have won two unshared Nobel Prizes. His first prize (1954) was awarded for research into the nature of the chemical bond and its use in elucidating molecular structure; the second (1962) recognized his efforts to ban the testing of nuclear weapons.”
After graduating from Oregon State University (then Oregon Agricultural College), he attended the California Institute of Technology (Caltech), where Roscoe G. Dickinson showed him how to determine the structures of crystals using X rays. He received his Ph.D. in 1925 for a dissertation derived from his crystal–structure papers.”
