The Theodore Harrington Collection contains items gathered by Theodore Harrington's mother and pertain to his time as an airman on the home front during World War II. The majority of the collection centers around his years of service in the Army Air Corps, from 1944-1945. Contained in the collection are folders with material created by Harrington or those around him, including letters, journal and memoir entries, and photographs. The letters are primarily from Harrington to either friends or his parents. The photographs feature servicemen posing with women or are of Harrington's family.
