He was born in Columbus, Ohio and studied at Pomona College and Oxford University. He went on to earn his Ph.D. from Cornell in 1913, where he would continue most of his scientific career. During a 1926 sabbatical spent at the University of Göttingen, he learned the newly developing quantum mechanics of Werner Heisenberg and Pascual Jordan.
