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 ca. 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 l920s. Also prominently mentioned are: Francis William Aston, Karl Auer von Welsbach, Niels Henrik David Bohr, William Henry Bragg, Johannes Broensted, Dirk Coster, Marie Curie, Charles Galton Darwin, Alexandre Dauvillier, Albert Einstein, Roland von Eotvos, Kasimir Fajans, Alexander Fleck, Fritz Haber, Martin Knudsen, Henry Gwyn Jeffreys Moseley, Hantaro Nagaoka, Walther Nernst, Ida Noddack, William Ramsey, Ricci-Curbastro, A. S. Russell, Ernest Rutherford, Erwin Schrodinger, Frederick Soddy, Edward Teller, Thomson, Georges Urbain, M. Volmer; Niels Bohr Institute, and University of Manchester.
