Fessenden, Reginald AubreyReginald Aubrey Fessenden, radio inventor (b at Milton-Est, Canada E 6 Oct 1866; d at Hamilton, Bermuda 22 July 1932). After attending Bishop's University, Fessenden joined Thomas Edison's laboratory in 1886 and later worked for Westinghouse, the US Weather Service and 2 American universities, making several fundamental discoveries in radio, including the superheterodyne principle, the basis of all modern broadcasting. In 1902 Fessenden formed his own company.
In 1906 he achieved 2-way voice transmission by radio between Machrihanish, Scotland, and Brant Rock, Massachusetts (Marconi had sent radio signals from England to Newfoundland in 1901, but only one way and in Morse code). On Christmas Eve 1906 Fessenden made the first public broadcast of music and voice. In 1910 he lost control of his company and thereafter lived in relative seclusion, although continuing his research. Many of his patents were widely adopted (without his consent) during WWI, and in 1928, in recognition of his contributions to radio technology, the US Radio Trust paid him $2.5 million.
