This interview was conducted as part of the Archives for the History of Quantum Physics project, which includes tapes and transcripts of oral history interviews conducted with circa 100 atomic and quantum physicists. Subjects discuss their family backgrounds, how they became interested in physics, their educations, people who influenced them, their careers including social influences on the conditions of research, and the state of atomic, nuclear, and quantum physics during the period in which they worked. Discussions of scientific matters relate to work that was done between approximately 1900 and 1930, with an emphasis on the discovery and interpretations of quantum mechanics in the 1920s. Also prominently mentioned are: Sam Allison, Svante August Arrhenius, Raymond Thayer Birge, William Henry Bragg, William Lawrence Bragg, Arthur Compton, Edward Condon, Marie Curie, Peter Josef William Debye, William Duane, Tatiana Ehrenfest, Paul Ehrenfest, Albert Einstein, Paul Darwin Foote, James Franck, Helmut Hasse, Arthur Llewelyn Hughes, Frederick Vinton Hunt, Mrs. Langevin, Paul Langevin, Irving Langmuir, Harvey Brace Lemon, Gilbert Newton Lewis, Hendrik Antoon Lorentz, A.
