The Mysterious Traveler was first heard on the Mutual Broadcasting
System on December 5, 1943. The program aired stories that were
written from various genres of fiction. Some episodes were science
fiction in nature, some were fantasy, and some were crime dramas.

Robert Arthur and David Kogan wrote and directed the episodes for
Mysterious Traveler.
Maurice Tarplin, who played the title role,
narrated the tales (much like the The Whistler radio program). Each
week, Mr. Tarplin invited listeners to take a journey on a train headed
"into the strange and terrifying" world of fiction.

The haunting wail of a distant locomotive provided great atmosphere
(and imagery) for the listening audience. Jack Ward, a NBC organist,
played sinister sounds from his organ during
Mysterious Traveler

The Mysterious Traveler aired on radio station, WOR.  WOR was the
New York flagship station of the Mutual Broadcasting System. Mutual
was considered one of the "Big Four" national radio networks during the
golden age of radio.

On September 16, 1952, the last episode of
The Mysterious Traveler
aired. There were over 300 episodes of The Mysterious Traveler
program. At the moment, only about 70 episodes survive in circulation.
"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!"
