Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-born inventor, who did a majority of his work in the United States and also claimed U.S. citizenship through his American-born father.

John M. Fessenden
John Milton Fessenden was born in Warren, Rhode Island, December 23, 1802, and died in Washington, D.C., on February 8, 1883, to John Fessenden (born 1770) and Abigail Miller Child (born 1783). His grandfather, also John Fessenden, was a member of the Massachusetts Provincial Congress during the American revolution and then after the successful introduction of a state constitution, state senator for seven years after the war. Fessenden was appointed to the United States Military Academy and graduated in 1824. In his second year at the academy a remarkable event occurred in his life; the cadet corps marched from West Point to ex-president John Adams' home in Peacefield, near Boston in the summer of 1821 to honor the ailing Adams.
