Reginald Aubrey Fessenden 1866-1932
· Fessenden, a Canadian born in East Bolton, Quebec worked as a tester and Chemist in the Edison Machine works of New York, and later at Edison's laboratory in New Jersey. Among his patents were the electrolytic detector - far more sensitive than other early methods of detection, and the process of 'heterodyning' a signal - mixing it with another frequency to create a 'sum' and 'difference' of the original frequency.
· Personally, he is said to have been a bit arrogant - using phrases such as 'Don't try to think - you haven't the brain for it'. He obtained over 500 patents in his lifetime, many for advances in the art of radio.
On Christmas Eve, 1906 he broadcasts speech and music to surprised shipboard operators. He broadcasts on 42 Kilohertz at 1 kilowatt. The programming includes a female voice singing a Christmas carol, a violin solo by Fessenden, and an invitation to report on reception.
