John F. "Jack" Martin

On 12/31/2019, Jack passed away surrounded by family and friends after a long and courageous battle with Parkinson’s disease. He was born and raised in Tremont, Pennsylvania, and attended LaSalle University in Philadelphia, attaining his Bachelor’s degree in Physics. His post graduate work included coursework at Massachusetts Institute of Technology. He enjoyed a long career at TEACOM, APG, and has patents on the rifle sights he invented during his tenure. His post-retirement career was in Computer Science and Digital Media, and he was famous for the wonderful slide shows he created way before they became popular. He was a huge early proponent of the benefits of Solar Energy, and lectured on the topic at Arizona State University. Despite all of his many accomplishments, he was most proud of his role as Father to his children. Jack was preceded in death by his Parents, Natalie Martin Carey, and John Carey, his Aunts and Uncles, Settimo, Anne, and Joseph, and his Grand-daughter, Katelyn Schwiegerath.
