 No complete list of Reichenbach’s doctoral students appears to be available. After coming to UCLA in 1938 he had at least six Ph.D students known to us. W. Bruce Taylor studied with him between 1949 and 1953, but we do not know about his subsequent career—he listed no academic affiliation in 1976. Melvin Maron and Norman Martin are listed by the Mathematics Genealogy Project as completing their Ph.D.s with Reichenbach in 1951 and 1952, respectively, but we know of no further record for them. Cynthia Shuster became a professor at Washington State University, from where she was fired during the McCarthy era for “corrupting the youth” by inviting Robert Oppenheimer to speak on campus. She continued her career at the University of Montana until her death. Hilary Putnam, who was at Princeton and then Harvard until his retirement, besides other important contributions less directly connected to Reichenbach, combined Reichenbach’s emphasis on learning in the limit with the theory of computation to create the foundations of computational learning theory, which remains a major theme in theoretical computer science. Until his death, Wesley Salmon, who taught at Washington State, UCLA, Northwestern, Brown, Arizona and Pittsburgh, was the philosopher who most prominently and loyally developed and defended Reichenbach’s views, especially but not exclusively his views on probability and on the justification of induction. Carl Hempel took his doctorate in Berlin with Reichenbach. After moving to the United States, he taught at Yale, Princeton and then Pittsburgh. Hempel’s work on confirmation was discussed by Reichenbach but had no connection to his own. Early in his career Hempel’s thought was more closely connected with Carnap’s logical approaches, while his later views were more closely allied with those of Thomas Kuhn, and in general his intellectual and personal relations with Reichenbach do not appear to have been close.
