The Falcon radio series premiered on the Blue Network on April 10, 1943, continuing on NBC and Mutual until November 27, 1954. Some 70 episodes were produced. “Drexel Drake” (a pseudonym of Charles H. Huff) created Michael Waring, alias the Falcon, a free-lance investigator and troubleshooter, in his 1936 novel, The Falcon’s Prey. It was followed by two more novels (The Falcon Cuts In, 1937 and The Falcon Meets a Lady, 1938) and a 1938 short story. In 1941, RKO made a movie, The Gay Falcon, based on a 1940 short story, “Gay Falcon,” by Michael Arlen, rechristening Arlen’s Gay Stanhope Falcon as Gay Lawrence aka the Falcon.
It became a film series, and its popularity led eventually to the radio series. No explanation for the nickname was ever mentioned in any of the dramatizations. The Michael Waring Falcon was also the hero in three late 1940s movies starring John Calvert, and a television series starring Charles McGraw.
