Bulldog Drummond is a classic American radio crime drama that aired on Mutual from April 13, 1941, to March 28, 1954. The show's central character, Bulldog Drummond, was created by British author H.C. McNeile and portrayed a relentless British investigator with a knack for crime detection and apprehending criminals. Drummond and his sidekick Denny (played by various actors over the years) solved many murder cases and dealt with radium thieves to counterfeiters. The show was initially set in Great Britain but later moved to the United States.

The series was known for its opening sequence, created by producer-director Himan Brown, featuring foghorn, footsteps, shots, and police whistles. The characters were played by notable actors such as George Coulouris, Santos Ortega, Ned Wever, Cedric Hardwicke, Everett Sloane, Luis van Rooten, and Rod Hendrickson. The show was written by Allan E. Sloane, Leonard Leslie, Edward J. Adamson, and Jay Bennett, with distribution handled by Mutual Broadcasting System and syndication by Chartoc-Coleman company.

Bulldog Drummond was later revived in 1953, with Sir Cedric Hardwicke in the lead role. However, this version of the show ran from January 3, 1954, to March 28, 1954, before it ended. Overall, the show was popular for its crime-solving and thrilling adventures in a wartime atmosphere.
