Abstract

This interview begins with a discussion of Babcock's childhood and youth around Mt. Wilson Observatory, with comments on father (Harold D. Babcock), Walter S. Adams, and Edwin P. Hubble. Also discussed in this interview: education at Caltech, University of California at Berkeley and Lick Observatory (1934-1939), and at Yerkes and MacDonald Observatories; work at MIT and Caltech on World War II hardware; astronomical instrumentation work, especially postwar Mt. Wilson-Palomar diffraction gratings; discovery of magnetic stars and studies of variations; work on solar magnetic fields (with father) and theory of solar cycle; comments on cosmology; discussion of Mt. Wilson and Palomar Observatories since the 1920s, especially under Ira Bowen's and Babcock's directorship (1963); internal administration; staff relations; dealings with Carnegie Institution and Caltech; discussion of Hale Observatories, 1930-1977; role of government funding in astronomy; guest investigators; allocation of telescope time; planning, funding, and construction of the Carnegie Southern Observatory at Las Campanas, 1963-1977. Also prominently mentioned are: Philip Abelson, Ed Ackerman, Carl David Anderson, Wilhelm Heinrich Walter Baade, Patrick Maynard Stuart Blackett, Vannevar Bush, Subrahmanyan Chandrasekhar, Crawford Greenewalt, Jesse Leonard Greenstein, George Ellery Hale, Caryl Haskins, Louis Henyey, Armin O.

Abstract

Childhood; early interest in science (astronomy). Member of Astronomical Society of the Pacific, 1928. Special student at University of California at Berkeley, 1931, with Donald H. Menzel’s help. Regular student from 1932; comments on teachers and fellow students at Berkeley Student Observatory. Summer assistantship at Lick Observatory (Nicholas Mayall, Arthur B. Wyse), life at Lick Observatory. To Harvard University in 1937 for graduate studies; comparison between Harvard and Berkeley/Lick; teaching assistant at Radcliffe; 3-year membership in Harvard Society of Fellows, from 1939, of enormous importance for his development; works with Menzel and James G. Baker on the Theory of Physical Processes in Gaseous Nebulae, 1937; Analysis of the Atmospheres of the A-type Dwarfs Gamma Geminorum and Sirius based on data from Louis Berman; Jesse Greenstein. Comments on Harvard Summer Schools, Harlow Shapley’ s Square.” Volunteer teacher of elementary physics courses from 1942 at Harvard. Lawrence Radiation Laboratory, 1943-1945; work involved evaluation of the chemists and the Counting Group’s output from the electromagnetic separation process. Job offer from University of Indiana (Frank Edmunson) accepted due to cutback at Radiation Laboratory. Indiana years, 1945-1948, very productive (drafts for two astrophysics books); problems getting telescope time at Yerkes Observatory and unsatisfactory living conditions leads to acceptance of a promising tenured position at Michigan, a center with very active research due to Leo Goldberg; Robert McMath’s influence in the department; Keith Pierce and Aller’s work on infrared solar spectrum. Work performed at Mt. Wilson Observatory and Dominion Astrophysical Observatory. Goldberg resigns in 1959; comments on Aller’s decision to leave Michigan; discussions of funding; “over-head” (Aller’s talk at an AAS Meeting); comparison of Lick Observatory and Kitt Peak Observatory policies. Work at Mt. Stromio Observatory, Australia on sabbatical visits, 1960, 1968-1969, 1977-1978. Overview of opinions of the present state of astronomy. Comments on personal life, wife and children.
