Mister Keen, Tracer of Lost Persons

Based loosely on the Robert W. Chambers novel Tracer of Lost Persons, the radio series Mister Keen, Tracer of Lost Persons was the longest-running radio series of all time, airing from 1937-55. The series began with Mister Keen operating as a missing person’s case investigator much like his literary counterpart. The series was produced by the radio factor of Frank and Anne Hummert and featured many of the same actors as appeared in their many soap operas.

Mister Keen began as a thrice-weekly serial in 1937 and continued in that format until November 1943 when it began a weekly half-hour program. It would continue on the air in 1955. It would revert to fifteen-minute episodes in 1954 until the last two months of its run when it would once again become a half-hour show for its last two months on the air.

The series began as a heartwarming series of mysteries that dealt with domestic and family problems in its lost-persons cases. In the post-War era, it became far more focused on murder cases. The series was known for its easy-to-follow scripts, frequent bouts of melodrama, and use of various standard mystery cliches. The series was lampooned by the comedy series Bob and Ray.
