In 1913, Sproul started his career briefly as an efficiency engineer in Oakland, California. During the
Great Depression, expansion of facilities stopped. After World War II, he served on the
Committee for the Marshall Plan. Sproul started to speak of UC's missions as "teaching, research, and public service", California governor
Earl Warren asked Sproul, his former classmate and fellow 1911 member of the University of California Band, to place his name in nomination for Vice President of the United States at the 1948
Republican National Convention in
Philadelphia, Pennsylvania. Sproul retired in 1958. He became active in the Save the Redwoods League (after being a member since 1921) and in the East Bay Regional Park District and served on the National Park Advisory Board. Before and during Sproul's presidency, the University of California's bureaucracy was highly centralized in Berkeley, but that was no longer politically viable by the time he retired. After 1900, the skyrocketing population of Southern California meant that Southern Californians were becoming the majority of everything—the state's population, then the state legislature, and then the Board of Regents—and they were fed up with long-distance micromanagement from Berkeley. UC Berkeley Chancellor
Clark Kerr succeeded Sproul in 1958 with a clear mandate for change from the southern regents. Oddly, Kerr kept Sproul around as president emeritus and allowed him to sit on the committee which developed the actual plans for decentralizing the university's bureaucracy—that is, for dismantling the empire in Berkeley which Sproul had carefully protected for so many years. Sproul participated in the committee's meetings, but had enough dignity to know when he had been beaten fair and square. He put up no opposition and all committee votes were unanimous. From Sproul's office as president emeritus, he gave a speech during the 1967
Free Speech Movement at Berkeley, by which he "contributed one of the few notes of humor in an otherwise grim confrontation." When student demonstrators broke into his office and scattered his papers, he told a reporter, "Nonsense. Nobody messed up my office. It always looks that way." ==Personal and death==
