Doc Holliday (baptized March 21, 1852, Griffin, Georgia, U.S.—died November 8, 1887, Glenwood Springs, Colorado) was a gambler, gunman, and sometime dentist of the American West.
Holliday was reared in Georgia in the genteel tradition of the Old South, graduated from the Pennsylvania College of Dental Surgery in 1872, and, already consumptive, moved west for drier climes. He practiced dentistry briefly in Dallas but soon discovered his prowess as a gambler, a poker and faro player, and began drifting throughout the West—Jacksboro, Texas; Pueblo and Denver, Colorado; Cheyenne, Wyoming; Deadwood, South Dakota; Dodge City, Kansas; Trinidad and Leadville, Colorado; and Las Vegas, New Mexico, ending up in Tombstone, Arizona, in 1880. During that period he gained a reputation as a drinker, fighter, and killer; he also probably married one Kate Elder.
Holliday had befriended Wyatt Earp in Dodge City and, when in Tombstone, joined the Earp brothers in the celebrated gunfight at the O.K. Corral against the Clanton gang. From then (1881) on, he was again a drifter (having abandoned Kate Elder), and he died five years later in Glenwood Springs, Colorado, where he had gone for treatment of his tuberculosis.
