Reginald A. Fessenden House
The Reginald A. Fessenden House is a historic house at 45 Waban Hill Road 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. The house was designated a National Historic Landmark in 1976 in recognition of Fessenden's accomplishments.
Invention of radio
In late 1886, Reginald A. Fessenden began working directly for Thomas Edison at the inventor's new laboratory in West Orange, New Jersey. Fessenden quickly made major advances, especially in receiver design, as he worked to develop audio reception of signals. The United States Weather Bureau began, early in 1900, a systematic course of experimentation in wireless telegraphy, employing him as a specialist. Fessenden evolved the heterodyne principle here where two signals combined to produce a third signal.
