About Elmer T. Cunningham
- Elmer Tiling Cunningham (September 1, 1889 – June 14, 1965) was an American entrepreneur and businessman, specializing in vacuum tubes and radio manufacturing.
- He is best known for being the most successful business person to produce counterfeit (AKA bootleg) or unlicensed vacuum tubes (1915-1920).
- Cunningham was in direct violation by infringing on the Fleming and De Forest vacuum tube patents.
- Unlike other businesses making unlicensed or bootlegged vacuum tubes, Cunningham was very aggressive in his advertising.
- Manufacturers of counterfeit vacuum tubes generally ended their activities after a lawsuit has been filed but Cunningham came out ahead after various lawsuits brought against him and his company, the Audio Tron Sales Company.
- His successes encouraged many others to do the same thing.
