Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian electrical engineer and inventor who received hundreds of patents in fields related to radio and sonar between 1891 and 1936 (seven of them after his death). Fessenden pioneered developments in radio technology, including the foundations of amplitude modulation (AM ...
A Fessenden oscillator is an electro-acoustic transducer invented by Reginald Fessenden, with development starting in 1912 at the Submarine Signal Company of Boston. [1] It was the first successful acoustical echo ranging device.
The list of Reginald Fessenden patents contains the innovation of his pioneering experiments. Reginald Aubrey Fessenden received hundreds of patents for devices in fields such as high-powered transmitting, sonar, and television.
On 23 December 1900, the Canadian-born American inventor Reginald A. Fessenden became the first person to send audio (wireless telephony) by means of electromagnetic waves, successfully transmitting over a distance of about a mile (1.6 kilometers,) and six years later on Christmas Eve 1906 he became the first person to make a public wireless ...
Fessenden barretter. The hot-wire barretter was a demodulating detector, invented in 1902 by Reginald Fessenden, that found limited use in early radio receivers.In effect, it was a highly sensitive thermoresistor, which could demodulate amplitude-modulated signals, something that the coherer (the standard detector of the time) could not do.
Electrolytic detector. The electrolytic detector, or liquid barretter, was a type of detector (demodulator) used in early radio receivers.First used by Canadian radio researcher Reginald Fessenden in 1903, it was used until about 1913, after which it was superseded by crystal detectors and vacuum tube detectors such as the Fleming valve and Audion ().
In January 1906, Reginald Fessenden achieved the first two-way transatlantic radiotelegraph transmission, exchanging Morse code messages between his stations in Brant Rock and Machrihanish, Scotland. (Marconi had only achieved one-way transmissions prior to his date).
The Reginald A. Fessenden House is a historic house in the village of Chestnut Hill in Newton, Massachusetts.It was the residence from 1919 to his death in 1932 of the inventor Reginald A. Fessenden (1866–1932), called "the father of radio broadcasting," because he was the first to broadcast the human voice and music by radio.
