Reginald Fessenden: The Father of Radio Broadcasting
Tuning into a Legacy
Reginald Fessenden is celebrated as the inventor who pioneered radio technology, laying the foundation for amplitude modulation (AM) radio. He achieved the remarkable feat of transmitting speech by radio in 1900 and successfully demonstrated the first two-way radiotelegraphic communication across the Atlantic Ocean in 1906.
Early Life and Education
Born on October 6, 1866, in East Bolton, Canada East, Fessenden was the eldest of four children to Reverend Elisha Joseph Fessenden and Clementina Trenholmes. His family moved frequently throughout Ontario, where he attended various educational institutions. Notably, he enrolled in the DeVeaux Military school at the age of nine and later attended Trinity College School in Port Hope, Ontario.
A Path to Innovation
After completing his education, Fessenden worked for the Imperial Bank at Woodstock before returning to his hometown in the Eastern Townships. He then attended Bishop's College School, where he earned a mathematics mastership teaching job and a scholarship to study in the college division at Bishop's University. During this time, the teenage Fessenden taught mathematics to younger students, including some older than himself, while simultaneously pursuing his own studies.
