Education, decision to go into physics. Environment at the University of California, Berkeley in early 1950s, especially Charles Kittel's group; Charles Overhauser, et. al. At Berkeley as a graduate student after Charles Kittel's arrival, 1950, Kittel's development of the department (after the loyalty oath); focus on solid state physics, mainly resonance physics (ferromagnetic resonance, cyclotron resonance); University of Chicago and Berkeley relationship. Cohen at Chicago's Institute for the Study of Metals, from 1952. Discussion of the established Institutes for Basic Research: Institute for Nuclear Studies (Enrico Fermi); Institute for the Study of Metals (Cyril Smith, Andy Lawson, Stuart Rice); Low Temperature Laboratory (Earl Long). Contributions in resonance physics, semiconductor physics (Kittel, Cohen, Albert Overhauser, Carson D. Jeffries), superconducting alloys (Bernd T. Matthias and John Hulm); semi-metals, crystal structure, band structure; Fermi surface and Fermi theory of liquids; Clarence Zener anecdote; University of Chicago model of an interdisciplinary research institute for materials science; Lars Onsager's theory (1951) and its stimulating effect; Cohen's encounter with Brian Pippard; General Electric consultant (Walter A. Harrison, free electron model interpretation); James C. Phillip's critical point spectroscopy; Pippard and Eugene I. Blount "missed" the Fermi theory of liquids. Philosophical summarizing on declaring fields "closed," importance of young people in positions of responsibility. Also prominently mentioned are: Luis Alvarez, Chuck Barrett, Robert Dicke, Leopoldo Falicov, Arthur Kip, Lev Landau; and General Electric Company Research Laboratory.
