Peter Michael Fattori

Surrounded by faith and love, Peter Michael Fattori of Saline, Michigan, passed away on Wednesday, January 14, 2026, at the age of 85. Born in Toronto, Ontario, on July 3, 1940, to Arthur (Ettore) and Ida (Mandarino) Fattori, Peter’s journey led him to the University of Michigan. There, he earned a Bachelor of Science in Mathematics and Physics, sparking a lifelong passion for logic and innovation. Peter dedicated much of his professional life to Comshare in Ann Arbor, where he rose through the ranks from computer programmer to hardware management and, eventually, senior leadership. An entrepreneur at heart, he later co-founded Northgate working alongside his son, Brett. He concluded his distinguished career at Gene Codes Corporation, where his dedication to complex problem-solving remained sharp until his retirement. Peter married the love of his life, Jean (Raymore), in 1961 at the age of 20 in Toronto. They began their married life in Ann Arbor, where they lived until 1984, when they moved to Saline. This year, they would have celebrated the 70th anniversary of their first date, a milestone that reflected their deep devotion to one another. In retirement, Peter and Jean enjoyed traveling throughout Michigan—especially Frankenmuth and Charlevoix—and spent many winters in Florida, where they made lifelong friends. They also shared a love of cruising and were able to visit Europe together. Peter was known as a humble, kind, and radically accepting man. He was always excited to connect and to learn something new about everything and everyone. He delighted in new gadgets and took great satisfaction in figuring out how things worked. Born a natural tinkerer and with an incredible eye for detail, Peter enjoyed helping his family with home improvement projects and was meticulous in his work—something clearly reflected in the home he and Jean created together. He especially loved his garden and took great pride in growing exceptional zucchini and tomatoes which he then used in his cooking. Peter loved preparing traditional Italian recipes passed down through his family, while also enthusiastically trying new dishes and sharing them with others. Peter’s greatest pride was his family. He is survived by his beloved wife, Jean; his son, Brett Fattori; and his daughter, Lisa (Steve) Anderson. He was a devoted grandfather to Jenna (Chris) Foley, Cassie Anderson, and Sydney Anderson. Most recently, he found great joy in his role as a great-grandfather to Donovan, Ava, and Patrick Foley. He is also survived by his sister, Mary Therese Carmichael, and his brother, Michael Fattori. Peter was reunited in heaven with his son, Christopher Fattori; his brothers, Robert and David Fattori; and his parents and many close relatives in Canada. His strong Catholic faith sustained him throughout his life, grounding him in trust in God and confidence in the truth of his journey home. Rooted in his Catholic faith, devoted to his beloved wife Jean, and deeply proud of his children, grandchildren, and great-grandchildren, Peter lived a life of quiet strength and generous love. We commend him to God with gratitude for the gift of his life and faith in the promise of eternal peace. “I am the resurrection and the life; whoever believes in me, even if he dies, will live.” — John 11:25 Friends may join the family for a time of visitation on Friday, January 30th from 10:30 A.M. to 11:30 A.M. at St. Andrew Catholic Church in Saline.
