Stock's Baker Lectures on "Hydrides of Boron and Silicon," was in part responsible for his choosing H. I. Schlesinger as his graduate research advisor at Chicago. His Ph.D. thesis (1938) dealt with the reduction of car-bony1 compounds with diborane. After a year of postdoctoral work with M. s. Kharasch, he became assistant to Schlesinger (with rank of instructor) and codiscovered sodium borohydride. He became assistant professor at Wayne (now Wayne State) University in 1943, exploring steric strains. He was promoted to associate professor in 1946. In 1947 he moved to Purdue University as professor. He was promoted to R. B. Wetherill Professor in 1959 and R. B. Wetherill Research Professor in 1960. Since his "retirement" in 1978, he has been R. B. Wetherill Research Professor
