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: Albert Einstein, Gustave-Robert Kirchhoff, Max Theodor Felix von Laue, Walther Nernst, Max Planck, Johannes Stark; Physikalische-Technische Reichsanstalt (Berlin), Stevens Institute, Universitt̃ Berlin, Universitt̃ Gt̲tingen.
