Edward S. Rogers, Sr. 1900-1939
49 Nanton Avenue was the childhood home of Edward Samuel Rogers Senior, inventor, businessman and pioneer in radio engineering and broadcasting in Canada. Fascinated by radio at an early age, he became the first amateur radio operator in Canada to transmit a signal across the Atlantic. In an office on the second floor, he experimented with electronics which later resulted in his perfecting the A.C. tube, the basis of the "Batteryless Radio". This permitted radios to run on household current. In 1925, he set up Standard Radio Manufacturing Company and introduced the batteryless radio at the C.N.E. In 1927 he upgraded his ham radio station to commercial status and called it CFRB, RB standing for "Rogers Batteryless".
