Elias Jackson "Lucky" Baldwin was "one of the greatest pioneers" of California business, an investor, and real estate speculator during the second half of the 19th century. He earned the nickname "Lucky" Baldwin due to his extraordinary good fortune in a number of business deals. He built the luxury Baldwin Hotel and Theatre in San Francisco and bought vast tracts of land in Southern California, where a number of places and neighborhoods are named after him.

Wyatt Berry Stapp Earp was an American lawman and gambler in the American West, including Dodge City, Deadwood, and Tombstone. Earp was involved in the famous gunfight at the O.K. Corral, during which lawmen killed three outlaw Cochise County Cowboys. While Wyatt is often depicted as the key figure in the shootout, his brother Virgil was both Deputy U.S. Marshal and Tombstone City Marshal that day and had considerably more experience in law enforcement as a sheriff, constable, and marshal than did Wyatt. Virgil made the decision to enforce a city ordinance prohibiting carrying weapons in town and to disarm the Cowboys. Wyatt was only a temporary assistant marshal to his brother.
