The Sundance Kid, born Harry Alonzo Longabaugh in 1867, was an American outlaw and member of the Wild Bunch gang. He gained fame for his involvement in bank and train robberies during the late 19th century, particularly in the American West. The Sundance Kid was known for his exceptional riding skills and marksmanship. He is often associated with Butch Cassidy, his close friend and partner in crime. Together, they became legendary figures in American folklore, symbolizing the rebellious spirit of the Old West. The duo's exploits were popularized in films, notably in the 1969 movie Butch Cassidy and the Sundance Kid.
