A graduate of the Pennsylvania College of Dental Surgery he became a gambler and gunfighter. Part of the inscription on his gravestone reads "One of the great gamblers and the speediest man with a six gun in the West. He lost his biggest bet when he died in a Glenwood Springs Sanatorium with tubercolis instead of being cut down by a bullet".
