File consists of a very personal reminiscence of James' graduate education at Harvard University under Edwin C. Kemble, including a fairly detailed discussion of his Ph.D. thesis work; his work at Purdue University in the 1930s with Karl Lark-Horovitz and visiting professor Lothar Nordheim; his work at the Massachusetts Institute of Technology Radiation Laboratory during the Second World War on night-fighter tactics, propagation of radar waves, and the stabilization of radar systems; his perceptions of the influences of the war on science in general; and reflections on his career. Respondents were asked to discuss their choice of physics as a profession and the course of their careers, their satisfactions and disappointments, the changes they saw in working and teaching conditions in the field, and relations within the community and with the society at large.
