The real Doc Holliday (1851-1887) was a Georgia dentist who, after a long process with much history in between, became a badass of the western U.S. Most notably, Doc Holliday was responsible for the death of Tom McLaury and possibly others in the Gunfight "at" the O.K. Corral. He and Wyatt Earp, along with Earp's brothers Virgil and Morgan, engaged in a thirty second gunfight in Tombstone, Arizona on 10/26/1881. Three men, Tom McLaury, Frank McLaury, and Billy Clanton were killed. The Earps and Holliday left alive, but in ensuing events, Morgan Earp was shot dead, leading to a vendetta by Wyatt Earp. He was joined by Holliday and the two have become legends of the west.
Their story was featured in several movies, including:
Tombstone, Wyatt Earp, Gunfight at the O.K. Corral.
Holliday died of tuberculosis in Colorado in November, 1887.
Doc Holliday was the most badass gunfighter to ever enter the West.
