Mr. Keen, Tracer of Lost Persons

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. English actor Bennett Kilpack [photo] began as Mr. Keen in 1937 with Arthur Hughes and then Phil Clarke stepping into the role later in the series. For 18 years the kindly Keen and his faithful assistant, Mike Clancy (Jim Kelly), entertained followers with their intuitive perception that kept listeners coming back for more.
