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.

Daniel McFarlan Moore Daniel McFarlan Moore (February 27, 1869 – June 15, 1936) was a U.S. electrical engineer and inventor. He developed a novel light source, the "Moore lamp", and a business that produced them in the early 1900s. The Moore lamp was the first commercially viable light-source based on gas discharges instead of incandescence; it was the predecessor to contemporary neon lighting and fluorescent lighting. In his later career Moore developed a miniature neon lamp that was extensively used in electronic displays, as well as vacuum tubes that were used in early television systems.

Clark cell The Clark cell, invented by English engineer Josiah Latimer Clark in 1873, is a wet-chemical cell (colloquially: "battery") that produces a highly stable voltage. In 1893, the output of the Clark cell at 15 °C was defined by the International Electrical Congress as 1.434 volts, and this definition became law in the United States in 1894. This definition was later supplanted by one based on the Weston cell.
