The Mysterious Traveler was an anthology radio series, a magazine, and a comic book. All three featured stories which ran the
gamut from fantasy and science fiction to straight crime dramas of mystery and suspense. Written and directed by Robert Arthur and David Kogan, the radio series
was sponsored by Adams Hats. It began on the Mutual Broadcasting System, December 5, 1943, continuing in many different time slots until September 16, 1952. The
lonely sound of a distant locomotive heralded the arrival of the sinister narrator (portrayed by Maurice Tarplin), who introduced himself each week in the following
manner: This is the Mysterious Traveler, inviting you to join me on another journey into the strange and terrifying. I hope you will enjoy the trip, that it will
thrill you a little and chill you a little. So settle back, get a good grip on your nerves and be comfortable—if you can! Cast members included Jackson Beck,
Lon Clark, Roger DeKoven, Elspeth Eric, Wendell Holmes, Bill Johnstone, Joseph Julian, Jan Miner, Santos Ortega, Bryna Raeburn, Frank Readick, Luis van Rooten,
Ann Shepherd, Lawson Zerbe and Bill Zuckert. Sound effects were by Jack Amrhein, Jim Goode, Ron Harper, Walt McDonough and Al Schaffer.
