Invention: Apparatus For Signaling By Electromagnetic Waves
Interesting Facts:
Born in East Bolton, Quebec, Canada, Fessenden was well-educated when he was young. When he was eighteen, he
became headmaster at a school in Bermuda. His work subsequently took him back to the U.S. to work with Thomas Edison and
to help George Westinghouse light the 1892 Columbian Exposition in Chicago. He then investigated wireless
radio communication with the U.S. Weather Bureau. Fessenden held over 200 patents, including a version of microfilm and an
early form of sonar.
Discovering a way to broadcast human voice by radio is only one
of Fessenden's accomplishments - during his life he came up with over 500other inventions including the Fathometer or depth finder which
are reflected in the words of the memorial above the vault of Fessenden's final
resting place. Reginald Fessenden is known for discovering amplitude modulation (AM) radio and explaining its scientific principles. On reaching adulthood, his dream was to transmit the sound of the human voice without wires. First, he perfected anew means of sending Morse code more effectively than Marconi.
