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.
History of radio
The invention of amplitude-modulated (AM) radio, so that more than one station can send signals (as opposed to spark-gap radio, where one transmitter covers the entire bandwidth of the spectrum) is attributed to Reginald Fessenden and Lee de Forest. On Christmas Eve 1906, Reginald Fessenden used an Alexanderson alternator and rotary spark-gap transmitter to make the first radio audio broadcast, from Brant Rock, Massachusetts. Ships at sea heard a broadcast that included Fessenden playing "O Holy Night" on the violin and reading a passage from the Bible.
