Description Osborne Perry Anderson was one of the five African American men to accompany John Brown in the raid on the Federal Arsenal at Harpers Ferry, Virginia (now West Virginia) in October 1859. Anderson was a free-born black abolitionist, born in West Fallow Field, Pennsylvania on July 27, 1830. Along with John Anthony Copeland Jr., another member of the Brown raiding party, Anderson attended Oberlin College in Oberlin, Ohio. He later moved to Chatham, Canada, where he worked as a printer for Mary Ann Shadd's newspaper, the Provincial Freeman. In 1858 Anderson met John Brown and eventually became persuaded to join his band of men determined to attack Harpers Ferry.
