  Reginald Fessenden - Wikipedia, the free encyclopedia
Fessenden was the son of a Protestant minister.
Fessenden is second only to Edison in the number of patents held in his name.
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.

 Radio's First Message -- Fessenden and Marconi   (Site not responding. Last check: 2007-11-06)
Fessenden's early experiments using spark transmitters were probably conducted at a frequency in the lower part of the HF band, since initially he was testing over short links of a few kilometres using 50-metre masts to support wire aerials.
Fessenden's equipment was working exceptionally well in the early hours of that morning, and (remarkable for that time) the echo of the telegraphy signals from the Scotland station could clearly be heard one fifth of a second later, having travelled the long way around the earth.
Fessenden's continuous waves, a new type of detector, and, his invention of the method as well as the coining of the word heterodyne, did not by any means constitute a satisfactory wireless telegraphy or wireless telephony system, judged by today's standards.

 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.

 USRC Fessenden, 1865
The Fessenden was one of two vessels contracted by the Treasury Department with Jesse Hoyt of New York on 10 February 1865 for a contract price of $162,000 per cutter.
Her refit, however, appears to have been something of a subterfuge as she was completely dismantled and her hull and fittings sold for a little over $3,000; the only major part of the vessel kept was her machinery.
The 1865 Fessenden's machinery was placed in a newly built iron hull which was successfully launched from her builder's yard on 26 April 1883.

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 remained firm in his views despite personal loss: during the war, two of his sons, Francis and James Deering, rose to the rank of general in the Union army, and a third, Samuel, was killed in action at Second Bull Run.
Fessenden believed that given the totality of the federal victory over the Confederacy, conservative plans for Reconstruction like Johnson's were absurd, and he argued firmly that it was the responsibility of the Congress to set Reconstruction policy, not of the Executive.

 Jurassic Radio, Part 4: Fessenden
Fessenden wound up getting a job as a tester for Edison in New York when he happened to be on the scene when a tester left the company.
Fessenden continued development work (that by this time was trying the patience of his investors, who wanted business, not science) to secure more efficient alternators and antennas on ever higher frequencies.
On December 24, 1906, Fessenden produced what broadcasting textbooks acclaim as the first broadcast of a program of music, readings and entertainment by radio to a tiny audience largely comprised of ship radio operators, most of whom were astounded to hear voices in their earphones.

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.

Fessenden never did graduate formally from a university, but because of the positions he held with Purdue University and the University of Pittsburgh he was hereafter referred to as Professor Fessenden.
Fessenden's sending apparatus consisted of a 40 horsepower steam engine driving a 35 kVA 125 cycle alternator, which in turn supplied current to transformers in which the voltage was raised to a value required to operate the spark.
Professor Fessenden was deeply disturbed by the sinking of the ocean liner Titanic on her maiden voyage to New York during the night of 14-15 April 1912.

 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.
Fessenden concluded that if the howl could be carried voices could too, and he decided that what was needed were very fast controlled waves of high frequency which would carry sounds.
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.

In 1900 Fessenden began to conduct experiments in wireless telegraphy for the United States Weather Bureau and became interested in voice transmission.
AM superimposed electric waves vibrating at the frequency of sound waves on a constant radio frequency, resulting in the modulation of the amplitude of the radio waves into the shape of sound waves and a steady transmission.
