ROBERT F. BACHER (1905–2004) INTERVIEWED BY MARY TERRALL June–August 1981, February 1983 ARCHIVES CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California Subject area Physics Abstract An interview in ten sessions, 1981 and 1983, with Robert F. Bacher, chairman of the Division of Physics, Mathematics, and Astronomy (1949-1962), Caltech’s first provost (1962-1969), and professor of physics, emeritus. He recalls his education at the University of Michigan and graduate work in physics at Harvard (1926-27) and Michigan, where he got to know J. R. Oppenheimer and the European physicists who joined the faculty and/or came for the summer sessions in physics: Goudsmit, Uhlenbeck, Fermi, Bohr, Ehrenfest, Dirac and others. Recalls postdoc year at Caltech (1930-31) working on atomic spectra; Oppenheimer’s lectures; Millikan’s cosmic-ray work. Spends 1931-1932 at MIT working with John Slater; Chadwick’s discovery of the neutron. Spends the next two years as a postdoc at Michigan, working with Goudsmit. Instructorship at Columbia, 1934; association with I. I. Rabi. Moves to Cornell in 1935; recollections of Hans Bethe; cyclotron work on neutron energies. Early 1941, joins the Radiation Laboratory at MIT, of which Lee DuBridge was director. Recalls start of Manhattan Engineer District; contacts with J. R. Oppenheimer and General Leslie Groves. Joins Los Alamos in June 1943 as head of experimental physics division; recollections of bomb work. Returns to Cornell in January 1946. Postwar development of high-energy physics; Acheson-Lilienthal Report on international http://resolver.caltech.edu/CaltechOH:OH_Bacher_R control of atomic energy. Establishment of the Atomic Energy Commission, fall 1946; he becomes a commissioner; moves to Washington, D.C.
