Clarence Addison Dykstra

Clarence Addison Dykstra ( ; February 25, 1883 – May 6, 1950) was a U.S. government administrator. He served as city manager in Cincinnati, Ohio, after teaching government at the University of Chicago. He then became president of the University of Wisconsin (1937–1945) as well as the 1st Director of the Selective Service System between 1940 and 1941. He then became provost of UCLA from 1945 to 1950.

He also served as the efficiency director of the city's Department of Water and Power for Los Angeles before World War II. He argued that the city needed to be further decentralized by expanding highways and creating suburban communities.

Dykstra was appointed by President Roosevelt to chair the 11-member National Defense Mediation Board, an effort to settle wartime disputes. He served from March 19 to July 1, 1941.

Because Dykstra had already served as a university president before coming to UCLA, he "was incensed at what he considered demeaning treatment of the provost by UC’s universitywide administration". During his five years at UCLA, he was popular and loved by the UCLA community.
