Also known as: Reginald Fessenden, Fessenden
Reginald Fessenden (1866–1932) was a Canadian-American inventor credited with some of the first audio radio transmissions, moving radio beyond Morse code to voice using amplitude modulation.1
Life and work
Where early wireless sent spark-gap pulses, Fessenden championed continuous-wave radio and the heterodyne principle, transmitting speech and music in the early 1900s.1
Contribution
His continuous-wave and AM techniques made broadcasting possible and influenced receiver design.
Legacy
Fessenden is remembered as a pioneer of voice radio, complementing Marconi’s telegraphy.
