Written and directed by Robert A. Arthur and David Kogan, the series began
on the Mutual Broadcasting System, December 5, 1943, continuing in many
different timeslots until September 16, 1952. Unlike many other shows of the
era, The Mysterious Traveler was without a sponsor for its entire run.
The lonely sound of a distant locomotive heralded the arrival of the malevolent
narrator, portrayed by Maurice Tarplin, who introduced himself each week in the
following manner: âThis 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 canâ!
