Born in Cleveland, OH he was proud to be a "Buckeye". His formative years were spent in Moreland Hills, Cuyahoga, OH, where his grandfather had a farm "Jack Horner's Fruit Farm" so Jack learned at a very early age how to plant/grow fruits and vegetables. When Jack was not working, he was always in a canoe on a lake or river, camping or hunting amongst nature where he found his solace. Jack absorbed so much knowledge during his working life, that he found fulfillment in teaching the younger generation. At heart Jack was an "old time" farm boy who loved tinkering with any type of equipment. He enjoyed going to tractor/car shows and would spend hours thoroughly examining them with a curious mind. One of his philosophies was "why purchase new when it's fixable" which left a never ending project list. Jack is loved and endeared by so many people that entered into his life and will be remembered deeply .
