 | | The eldest son of an Anglican minister, Reginald was born October 6th, 1866 in Knowlton, Quebec, Canada, but with his parents, Elisha Joseph Fessenden and Clementina Fessenden (nee Trenholme), at the age of five moved to Fergus (north of Guelph), Ontario and later to Chippawa near Niagara Falls. |
 | | Fessenden and his assistant Thiessen had perfected Morse transmissions using a new generator they had bought, and in October of his first year Fessenden experimentally hooked up a microphone to the improved system. |
 | | Fessenden was an incredible character: A holder of over five hundred patents, he also invented sonar, the depth sounder, carbon tetrachloride, the beeper/pager, the voice-scrambler, the radio compass (known today as LORAN), the tracer bullet and, yes, the automatic garage-door opener. |
