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: Niels Henrik David Bohr, Max Born, Richard Courant, Peter Josef William Debye, David Mathias Dennison, Albert Einstein, Enrico Fermi, James Franck, Werner Heisenberg, Gerhard Herzberg, Lev Davidovich Landau, Ernst Mach, Misch, Robert Sanderson Mulliken, Leonard Nelson, H. Nohl, Frau Pauli, Robert Wichard Pohl, Henri Poincar,̌ Carl Runge, Schoenhals, John Clarke Slater, Arnold Sommerfeld, Thomas, Emil Wiechert; Universitt̃ Gt̲tingen, and Universitt̃ Marburg.
