John Harris Rogers (1863-1930) served in Texas law enforcement for more than four decades, as a Texas Ranger, Deputy and U.S. Marshal, city police chief, and in the private sector as a security agent. He is recognized in history as one of the legendary ""Four Captains"" of the Ranger force that helped make the transition from the Frontier Battalion days into the twentieth century. Rogers participated in the Brown County fence-cutting wars, the East Texas Conner Fight, the El Paso/Langtry Prizefight, the riots during the Laredo Quarantine, and the hunts for Hill Loftis and Gregorio Cortez.
