The Logan Collection consists of Logan's Army discharge papers (1919; 1931); his parole papers for a second degree murder conviction; correspondence with the Veterans Bureau concerning his pension and possible parole from prison; and, miscellaneous personal papers.

John B. Logan, an African American soldier, was born in Morrillton, Ark. and enlisted in the U.S. Army (1914). Discharged in 1919, Logan subsequently reenlisted (1919) and was discharged for the second time as a Sergeant, 10th Cavalry, U.S. Army, Ft. Huachuca, Ariz. (1931) following his conviction for murdering a woman named Concha Silvas who had stolen his life savings. Logan received a sentence of from twenty-five to forty years in the Arizona State Penitentiary, Florence AZ. His sentence was commuted by the Governor (1936) and he subsequently spent some time in the San Francisco Veterans Hospital for treatment of service related injuries before being arrested for hit-and-run driving in San Joaquin County (1939). Nothing is known of Logan's life after that date.

Collection is open for research.
