Warren Dorn
Los Angeles County Supervisor, 1956-74

Warren M. Dorn represented the Santa Clarita Valley as Los Angeles County's 5th district supervisor from 1956 to 1972. Dorn, a conservative Republican, followed Roger W. Jessup in 1956 and lost reelection in 1972 to KABC television commentator Baxter Ward, a Democrat. (The office is nonpartisan.)
