Frank Clinton Mitchell was born on 15 January 1896, in St. Louis, Missouri, to John C. and Alvida (Septon) Mitchell. He had one brother, Charles Mitchell. Frank married Edna E. Kessler and had two sons, Frank W. Mitchell and John C. Mitchell. Frank died on 19 October 1977 of a heart attack. Mitchell worked in Little Rock, Arkansas, at the hospital in Camp Pike. After the U. S. entered World War I and rumors of a draft began circulating, he decided that rather than be drafted, he would join the Navy. On June 14, 1918, Mitchell enlisted in the United States Naval Reserve and trained at Camp Farragut (Great Lakes, Illinois). He also served at the Great Lakes Naval Training Station, Bay Ridge Barracks (New York), and the U.S.S El Sol, on which he sailed to France. Mitchell held various jobs in the Navy. He worked as a plumber, steamfitter, as a foreman during water main construction, and as a ship fitter. In 1918, while serving at the Great Lakes Naval Station, Mitchell contracted both the Spanish flu and the German measles. He mentions that many servicemen at the station succumbed to the flu. Mitchell was released from active duty on September 2, 1919, and was discharged from the U.S. Naval Reserve Force on September 30, 1921. In 1942, Mitchell founded Frank C. Mitchell Co., plumbing and utility contractors, and was the company’s president until his retirement in 1961. He was also active in politics and his community. Mitchell was a candidate for judge in the second district in the St. Louis County Court in 1940. He was a member of the Mt. Mariah Lodge No. 40 A.F. and A.M. for 58 years and also the Ivanhoe Commandery No. 8 Knights Templar in St. Louis and the Order of the Eastern Star, Valley Park Chapter No. 505. Mitchells’ grandfather, Joseph C. Mitchell married Rebecca Jane Harris in New York on 7 November 1852. Joseph served in the 10th and the 101st Illinois Infantry Volunteers in the Civil War.
