In this interview, David Zierler, Oral Historian for AIP, interviews Raymond Sawyer, professor of physics emeritus at the University of California at Santa Barbara. Sawyer recounts his childhood growing up in many towns in the Midwest as a function of his father’s frequent job transfers. He discusses his undergraduate studies at Swarthmore College, where he developed his interest in physics, and he explains the atmosphere of wide career opportunity in the age of Sputnik. Sawyer describes his graduate research at Harvard, where he worked in Norman Ramsey’s molecular beam lab. He explains how Julian Schwinger came to be his advisor and he describes his dissertation study on symmetries and the weak interactions of elementary particles. Sawyer discusses his postdoctoral research at CERN where he joined the theory group and where he studied the decay of a charged pion. He describes his second postdoctoral appointment at the University of Wisconsin and his work in quantum field theory at the Institute for Advanced Study which he did at the invitation of Robert Oppenheimer. Sawyer explains the series of events leading to his decision to join the faculty at UC Santa Barbara, and he discusses his role in the formation of the Institute for Theoretical Physics. He explains his invention of charged pion condensation and he describes his work in university administration. At the end of the interview, Sawyer reflects on his contributions throughout his career, and he explains how he has kept active in the field during retirement.
