The interview describes his early education in his hometown of Richmond, Michigan; his undergraduate education and his interest in chemistry; his years at Stanford University and his later years at the California Institute of Technology (Caltech) as a graduate studen and research fellow, working with Carl Anderson; and receiving the Fermi award. Neddermeyer offers recollections of Robert Andrews Millikan, whose interest in cosmic rays was closely bound to the work he and Anderson were doing; of Fritz Zwicky, Richard C. Tolman, and Harry Bateman; and of J. Robert Oppenheimer, both at Los Alamos and at Caltech, where he was a visiting professor in the spring term in the 1930s.
