John O. Crosby was born a
slave in Crosbyville,
Fairfield County, South Carolina, on December 22, 1850, to Sylvian and her master, Thomas Crosby. His mother was from
Richmond, Virginia. He was apprenticed to the carpenter's trade. In 1860, Thomas Crosby died and his estate was sold. Mary Q. Crosby purchased Crosby for $1,260. In 1864, Mary Crosby married William Stanton, and Crosby's apprenticeship ended and he moved to Shelton's Depot. Stanton was drafted into the
Confederate States Army in the
American Civil War in 1864, and John went along. Stanton was assigned duty as a guard of a prison for Federal soldiers in Florence, South Carolina, near Columbia. Stanton was friends with Robert Stark Means, commander of the prison, and Stanton was made suttler to the prisoners. Crosby's proximity to headquarters gave him the chance to occasionally act as drummer. Crosby was well liked, and used his privileges to occasionally help Federal prisoners escape and to give to the prisoners reports about Confederate movements. After the war, Crosby endeavored to gain an education. He joined the
Union League and became involved with county politics. In 1869, he was appointed by governor
Robert Kingston Scott as census taker. He entered
Biddle University in the fall of 1869 and
Shaw University in 1870, graduating in 1874 He later became the first African-American man to graduate from the
National School of Elocution and Oratory. ==Career==
