Reginald Fessenden

Reginald Fessenden

This Canadian spent much of his working life in the U.S. where he developed a way to combine sound and radio carrier waves. His first effort to transmit this mixed signal-to a receiver where the carrier wave would be removed and the listener could hear the original sound-failed. However, in 1906, using Alexanderson’s alternator, Fessenden made the first long­ range transmission of voice from Brant Rock, MA.
