Philadelphia until 1950 when he joined Piasecki Helicopter Company, later named Vertol Aircraft Corporation. In 1960 the Boeing Company acquired Vertol, and in 1961 he became Director of Administration for Boeing-Vertol with the responsibility for Contracts, Finance, Legal, and Industrial relations and Planning. In 1963, with his wife and thirteen children in tow, he moved from Boeing-Vertol in Philadelphia to Boeing Corporate headquarters in Seattle WA. He retired from Boeing in 1987 as Director of Contract Policy. Since moving to Washington, he was on the board of directors for Seattle Archdiocesan Catholic Youth Organization and Seattle Youth Symphony. He also served for three years as director of the Seattle Urban League. He was a devoted Catholic and active member of the choir at Sacred Heart Church in Bellevue and then at St. Francis Church in Chelan. He was a member of St. Teresa of Calcutta Church in Woodinville at the time of his death. Jack and Dottie, his beloved wife of 73 years, were devoted to their family. Their house, whether it was in Philadelphia PA, Medina WA, or Chelan WA was always open to their extended family and many friends. Their children all have fond memories of Sunday dinners and holidays in Philadelphia when their house was filled with a loving family of grandparents, aunts, uncles, and cousins. Laughter, good food, singing and dancing were enjoyed by all. The family traditions grew in WA as numerous grandchildren emerged on the scene. Family parties and games sometimes lasted until wee hours of the morning. Jack was always the heart of the party, leading the sing-alongs with his perfect pitch and booming voice. He made the weddings of his children and grandchildren extra special by serenading the bride and groom with his rendition of "Sunrise, Sunset". Jack and Dottie spent most of their final 20 years together in their beautiful retirement house - "Teetering on the Brink" - overlooking Lake Chelan in central Washington State, where they continued to host innumerable friends, guests and wonderful family gatherings. Many have been lucky enough to have had "happy hour" with them while overlooking the lake and hearing tales of their love story, with Jack making Dottie's Manhattan after she finished her crossword puzzle and tea. Their devotion to each other was evident as they sang "Our Love Affair" whenever they had an audience, which was quite often as they were always surrounded by family, friends and many "adopted persons". Jack touched the lives of so many - far more than just his enormous and wonderful family - with his unending kindness, generosity, wit, humor, and grace. He had a way of making everyone around him feel welcome, wanted, and important - even perfect strangers. He was everything one could ask for in a husband, father, grandparent, brother, uncle, friend, in-law or person.
