John was born in Jamaica, Long Island, New York. He was fascinated by electronics at an early age and earned his Novice amateur radio license WV2EGR in 1957 followed shortly thereafter by a General ticket as WA2EGR.

After college, John went to work as a microwave engineer. He designed and produced some of the first low noise solid state microwave amplifiers.
