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.
