Mr. Keen, Tracer of Lost Persons

Long-running American mystery series
from archive.org

Mr. Keen, Tracer of Lost Persons was one of radio's longest running shows, airing October 12, 1937 to April 19, 1955, continuing well into the television era. It was produced by Frank and Anne Hummert, who based it upon Robert W. Chambers' 1906 novel The Tracer of Lost Persons. The sponsors included Whitehall Pharmacal (as in Anacin, Kolynos Toothpaste, BiSoDol antacid mints, Hill's cold tablets and Heet liniment), Dentyne, Aerowax, RCA Victor and Chesterfield cigarettes. It aired on the NBC Blue network until 1947, when it switched to CBS.

Bennett Kilpack began as Mr. Keen in 1937 with Arthur Hughes and then Phil Clarke stepping into the role later in the series. The kindly Keen and his faithful assistant, Mike Clancy (Jim Kelly), entertained listeners for 18 years. With 1690 nationwide broadcasts, Mr. Keen was the most resilient private detective in a namesake role. The nearest competitors were Nick Carter, Master Detective (726 broadcasts), The Adventures of Sherlock Holmes (657) and The Adventures of the Falcon (473). Only 59 of the 1690 Mr. Keen programs are known to survive.

Richard Leonard directed scripts by Barbara Bates, Stedman Coles, Frank Hummert, Lawrence Klee and Bob Shaw. James Fleming and Larry Elliott were the announcers. Al Rickey's band provided the background music, including the program's theme, "Someday I'll Find You."
