orig. John Henry Holliday
(baptized March 21, 1852, Griffin, Ga., U.S.
died Nov. 8, 1887, Glenwood Springs, Colo.) U.S. gambler and gunman.
After graduating from dental school in 1872, he moved to the drier climate of the West to help treat his tuberculosis. After practicing dentistry briefly in Dallas, Texas, he took up gambling, and he began drifting throughout the West, finally settling in Tombstone, Ariz., in 1880. There he joined Wyatt Earp and his brothers in the famous gunfight at the O.K. Corral (1881). Having earned a reputation as a gunman, he resumed his drifting; five years later he died of tuberculosis at age 35.
