	Reginald Fessenden - Wikipedia, the free encyclopedia
		Reginald Aubrey Fessenden (October 6, 1866 - July 22, 1932) was a Canadian inventor born in East Bolton, Quebec, the son of a Protestant minister.
		When Reginald Fessenden was a child, he moved with his family to Ontario, where, from an early age, he showed an interest in mathematics far beyond what was expected for his years, conducting experiments that often both astounded and horrified his parents, who made certain that he received a high-quality education.
		Fessenden then became professor of electrical engineering at Purdue University, and a year later he was named head of electrical engineering at Western University of Pennsylvania, the institution that was to become the modern University of Pittsburgh.

	Adventures in CyberSound: Fessenden, Reginald A. (Aubrey)
		Fessenden also invented the heterodyne system of radio reception, the sonic depth finder, the radio compass, submarine signaling devices, the smoke cloud (for tank warfare), and the turboelectric drive (for battleships).
		Fessenden further contributed in 1902 to the development of radio by demonstrating the heterodyneprinciple of converting high-frequency wireless signals to a lower frequency that is more easily controlled and amplified.
		Fessenden held over 500 patents by the time of his death, including ones for a high frequency alternator, a fathometer, a sonic depth finder and submarine signalling devices.

	World's first radio voice broadcast from Mass. coast in 1906
		Reginald A. Fessenden arrives, sets up the National Electric Signaling Co. and proceeds to make Communications History with many improvements to the state of the art as known then.
		Fessenden was ultimately successful, and on December 21, 1906 gave a demonstration of the new alternator-transmitter to invited representatives from a number of organizations.
		For this purpose Professor Fessenden has designed a highly ingenious type of relay, using differential windings on the cores of magnets, between the poles of which is mounted an armature attached to the electrode of a microphonic transmitter chamber.

	An Unsung hero - Reginald Fessenden, the Canadian inventor of radio telephony
		Fessenden could truly lay claim to be the inventor of radio and he fully expected the world to beat a path to his door.
		Reginald is mentioned as one of her four sons, "inventor of the wireless telephone, the radio compass and the visible bullet for machine guns, he also invented the first television set in North America in 1919."
		Fessenden theorized that the fast frequency could be broadcast with program information, and a receiver could isolate the program information from the carrier and leave sound for his listeners.

	Reginald Fessenden - Radio's First Voice
		Fessenden's breakthrough was marred by a legal dispute over patent rights - a problem that would dog his career.
		In the years that followed, Fessenden invented a wireless system for submarine communication, devices to detect enemy artillery and locate enemy submarines, and an ocean depth device, called the "fathometer." With growing interest in radio in the 1920s, governments began issuing broadcast licenses.
		Yet Fessenden was all but forgotten after his death and denied his rightful place as a pioneer of radio.

		Fessenden then became professor of electrical engineering at Purdue University, and a year later Westinghouse arranged that he become chief of electrical engineering at Western University of Pennsylvania and conduct research for him.
		Rather than submit, Fessenden complained to President Theodore Roosevelt, but his letter was returned to the Bureau and he was forced to resign.
		Fessenden, then 62 and with a heart condition, decided to return to Bermuda where he had met his wife, Helen, more than 40 years earlier.

	Reginad Fessenden Biography
		While engaged in further research, Fessenden developed and patented some of his own inventions, one of which, microphotography, is of great importance today and is used by banks and business concerns as well as libraries and other professional institutions throughout the world for 'mini-recording' of cheques, documents, etc.
		Fessenden was also called to a formative commission meeting relative to harnessing the enormous potential power of Niagara Falls, but his ideas proved too advanced for acceptance by Adam Beck and others.
		Spurred on by this success, Fessenden improved the efficiency of his high frequency alternator and with a new type of umbrella antenna of his own design, both stations were in regular communication.

		Fessenden conceived of a continuous wave, in which the amplitude would be modulated at the transmitter and decoded at the receiving end.
		Fessenden, at this moment the world's first announcer, then played an Edison wax-cylinder recording of Handel's Largo, becoming the first D.J. (or should that be C.J.?) He wound up his program by playing 'O Holy Night' on his violin and singing the last chorus, becoming the first broadcast vocalist and musician.
		Fessenden was an incredible character: A holder of over five hundred patents, he also invented sonar, the depth sounder, carbon tetrachloride, the beeper/pager, the voice-scrambler, the radio compass (known today as LORAN), the tracer bullet and, yes, the automatic garage-door opener.

	Transactions of the American Philosophical Society Held at Philadelphia For Promoting Useful Knowledge Volume 89
		Fessenden was born in 1866 in East Bolton, Canada, on the shores of Lake Memphrémagog in Quebec, close to the Vermont border.
		Fessenden also noted, as a by-product, that transmission through air for distances much shorter than those involved in transatlantic reception was good in many regions of wavelength between 1 and 50 meters, later to be of interest for short wave communication and radar.
		Fessenden's measurements and decisions concerning the wavelength range to use for long distance transmission established something in the nature of an international standard until the early 1920s, when amateur operators carried out successful transatlantic broadcasts using equipment operating in the lower megahertz region.

	Nikola Tesla -- Guided Weapons & Computer Technology
		During the review period, the Patent Office notified Tesla that another patent application for a similar concept had been received from Reginald Fessenden and the office was directing an Interference investigation to determine priority.
		The document, "Nikola Tesla vs. Reginald A. Fessenden," which is no longer on file at the U.S. Patent Office, contains Tesla's own depositions as well as those of his closest and most trusted associates, George Scherff and Fritz Lowenstein.
		In addition to describing Tesla's "individualization" techniques for obtaining secure noninterferable radio communications—the patent is today recognized as the fundamental AND logic gate, a critical element of every digital computer—the interference record reveals that essential features of the spread-spectrum techniques of frequency-hopping and frequency-division multiplexing have their roots in the resulting patents.
