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, Bragg, Louis de Broglie, Constantin Carathǒdory, Frank Clive Champion, Peter Josef William Debye, Max Delbr ck, Enrico Fermi, Otto Halpern, Werner Heisenberg, Friedrich Hund, Lev Davidovich Landau, Ettore Majorana, Walther Nernst, Heinrich Ott, Wolfgang Pauli, Max Planck, Robert Wichard Pohl, Arnold Sommerfeld, Albrecht Unsl̲d, Hermann Weyl, Wilhelm Wien; Universitt̃ Berlin, Universitt̃ Leipzig, Universitt̃ M nchen, Univeristy of Cambridge, and Zeitschrift f r Physik.
