By the late 1940s, many young researchers whom Struve invited to Yerkes became established scientists. This created friction, as they did not want to follow his every word and were building their own careers. In 1947, Struve resigned as director of Yerkes Observatory and became chairman of the astronomy department at Berkeley and director of the Leuschner Observatory. He was succeeded by Kuiper at Yerkes; their relations were strained at times because of Struve's tendencies to keep control of Yerkes management. There were also rumors of similar strains between Struve and Chandrasekhar, but they were always dispersed by the latter, who insisted that Struve always kept scientific relations with his colleagues above the administrative ones. One reason for Struve's move to Berkeley was his tiredness of bureaucracy. In Berkeley, he was spending more time with personal research and students than ever before.
