The oral history with Irwin “Red” Diamond gives an insider’s view of the College of Marin over a forty-year period of growth and change. By extension, it also provides insight into the community college movement in the latter half of the twentieth century and the Marin County community which the college served. Mr. Diamond grew up in the 1920s and 1930s in Oakland, California, and attended the University of California at Berkeley, where he played varsity basketball, took part in student affairs, and majored in physical education—the best preparation, he had been told, for an administrative career in education. He coached the Cal freshman basketball team before entering the army. After wartime service in the Pacific, he returned to the Bay Area, met his future wife while teaching at Liberty Union High in Brentwood, and in 1947 was hired as basketball coach at the College of Marin. He launched his career at the College of Marin by taking his first-year basketball team, composed entirely of ex-GIs, all the way to the top; they returned home as community heroes when they won the national championship of their division. He soon became athletic director and in 1957 was appointed dean of students and director of guidance. In this role, and later as president of the Kentfield campus and district superintendent, Diamond initiated a whole array of new student services and new educational programs—detailed in the oral history—to meet the changing needs of the times and of the Marin County population. He also founded the College of Marin Foundation as a vehicle for providing additional support for the college.
