Roger Guy Mack, age 86, died Tue. Dec. 8, 2020, at Pine Run Health Center, Doylestown. Born Jan. 4, 1934, in Northampton, MA, he was the son of the late Glenn and Margaret (Warriner) Mack, the brother of the late Joyce Nelson, and the husband of Loraine (Tukey) Mack, to whom he was married 63 years. Following high school graduation, Roger joined the Army and ended up in the 353rd division of Army Security, and was stationed in Germany during the Korean War. Upon completion of his tour, he attended the University of Massachusetts and later got his Master's degree from Rensselaer Polytechnic Institute in Materials Engineering. He worked as a Metallurgical Engineer first for Hamilton Standard, and then ran a lab for American Bosch for many years before coming to Pennsylvania where he eventually founded Vacubraze, his own vacuum heat treat company. He was an active member and contributor to the American Society for Metals (ASM). Roger was an expert in failure analysis and his skills were in high demand throughout his career. In addition to his professional life, Roger was an active member of the community of Somers, Connecticut. He was a Rotarian as well as an elected Director of the Somers Board of Education. He coached girl's softball while his daughters played. Roger was a faithful volunteer at church, serving as Treasurer at Somers Congregational Church for many years before moving to Pennsylvania and joining the North and Southampton Reformed Church, then the Quakertown United Church of Christ, and finally, Pleasantville United Church of Christ. Roger was a native New Englander, and always had his fishing pole ready for a roadside stop in the foothills of the Green and White Mountains. He graduated to deep sea fishing later in life, and loved to spend summer weekends bottom fishing off the coast of Newburyport. He never lost his love for gardening and he spent a lot of years working on his golf game. Roger and Loraine enjoyed travel in retirement and enjoyed many cruises and visits to places he had previously seen only in a professional capacity. Roger enjoyed he and Loraine's annual stay in Naples, Florida for more than a decade. Roger's favorite hobby was woodworking in his basement workshop. He designed rooms, refurbished basements, built custom furniture, and handcrafted coveted annual Christmas gifts with his wife Loraine. Many of his family members and friends are blessed to have one or more of Roger's hand-crafted items in their possession. Finally, one cannot remember Roger without recalling his wry sense of humor. He was always quick with a joke, and he kept his family and friends entertained with his sharp wit. He adored his family, and derived great joy from his grandchildren and great grand-children. Roger spent the last two years in the care of the Garden at Pine Run, where he was visited frequently by family and was able to work on his puzzles, a favorite activity. He kept the staff laughing and was rewarded with new relationships and exceptional care. His beloved Loraine was a faithful caretaker and was holding his hand in his final moments. In addition to his wife, Roger is survived by daughters Lorie Terwilliger (husband Michael), Karen Sterling (husband Steven), and Donna Mack, grandchildren Kevin, Jaclyn, Rebecca, Eric, Caroline, Tyana, Ryan, Chelsea, Sarah, Dylan, and Alex, and great-grandchildren Dominic, Lucas, Scarlett, Brady, Sterling and Emma. Services and interment will be private and at the discretion of the family.
