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 1920s. Also prominently mentioned are: Harald Bohr, Niels Henrik David Bohr, Max Born, Lǒn Brillouin, Louis de Broglie, Paul Adrien Maurice Dirac, Th. de Donder, John Ray Dunning, Paul Ehrenfest, Albert Einstein, Enrico Fermi, Otto Robert Frisch, Gruenbaum, Werner Heisenberg, Ernst Pascual Jordan, Oskar Benjamin Klein, Hendrik Anthony Kramers, Lev Davidovich Landau, Nevill Francis Mott, Wolfgang Pauli, Rudolf Ernst Peierls, George Placzek, Edgar Rubin, Erwin Schrd̲inger, John Von Neumann, Eugene Paul Wigner; Universitt̃ Gt̲tingen, Universit ̌de Liege, and Universit ̌libre de Bruxelles.
