Radio and Television Pioneers: A Patent Bibliography
Each of the U.S. patents of forty radio and television inventors is cited in chronological order, giving the researcher a sense of the overall development of each inventor's work from the beginning of radio in the nineteenth century through 1978. Great and lesser patents are listed, including Lee de Forest's Audion (the radio tube) and transistor; Edwin Armstrong's side-band FM and superheterodyne circuits; David Sarnoff's secret radio signaling system; William Dubilier's electrical condensers, along with his better mousetrap; John Stone's many important radio telegraphy and tele-phony devices, plus his reinforced soap cake; and many others. Kraeuter includes complete citations to over 3,000 patents.
