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: Ernst Back, Niels Henrik David Bohr, Max Born, Constantin Carathǒdory, Peter Josef William Debye, Paul Ehrenfest, Albert Einstein, Walther Gerlach, Samuel Abraham Goudsmit, Werner Heisenberg, Heinrich Mathias Konen, Peter Lertes, Fritz London, Erwin Madelung, Wolfgang Pauli, Max Planck, Erwin Schrd̲inger, Arnold Sommerfeld, Otto Stern, George Eugn̈e Uhlenbeck; Artillerie Pr fungs-Kommission, Universitt̃ Gt̲tingen, Universitt̃ Marburg, Universitt̃ M nchen, Universitt̃ T bingen.
