Early contacts with Maria Goeppert Mayer, collaborations with her on uranium explosives for Los Alamos at Columbia University and on stability of neutrons at University of Chicago Nuclear Institute, reflections on meeting with Joseph Mayer while she was terminally ill. Also prominently mentioned is: University of California at San Diego.

Family background, early education, and science-technology interests in California and Oregon; Willamette College and radio electronics; contacts with E.O. Lawrence; career as graduate student at University of California, Berkeley, 1942-1949; war work at Berkeley Radiation Laboratory and Los Alamos; security; attitudes toward Trinity test and Hiroshima; postwar political involvement; big machines and general comments on postwar physics.

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: Max Born, Leon Brillouin, Dirk Coster, Peter Josef William Debye, Albert Einstein, Werner Heisenberg, William Vermillian Houston, Max Theodor Felix von Laue, Wolfgang Pauli, Erwin Schrödinger, H. Seeliger, Arnold Sommerfeld, Johannes Stark, Wilhelm Wien; Universität Leipzig, Universität München, and Universität Zurich.

World War I developments in electronics in relation to French and British Armies; post-war revitalization of Physics Department at Columbia Univ.: Pupin Laboratory; effect of quantum mechanics; growth of nuclear physics; graduate physics during the 1920’s and Depression years; Pegram’s relation to APS; personal satisfactions in professional career.
