Have Gun Will Travel was a popular American Western television series that aired on CBS from 1957 through 1963. It was the #4 show in the Nielsen ratings in its first year, and #3 for the next three years. It was one of the few television shows to spawn a successful radio version. The radio series debuted on November 23, 1958. The show followed the adventures of Paladin, a gentleman-turned-gunfighter played by John Dehner on radio, who preferred to settle problems without violence, yet, when forced to fight, excelled. Paladin lived in the Carlton Hotel in San Francisco, where he dressed in semi-formal wear, ate gourmet food, and attended opera. In fact, many who initially met him mistook him for a dandy from the East. When working, he dressed in black, used calling cards and wore a holster which carried characteristic chess knight emblems, and carried a derringer under his belt.
