Duane Allen Thorsheim, 90, passed away peacefully at home with his wife by his side on November 21, 2023. Born on September 2, 1933, in Austin, Minnesota, Duane was the youngest of three children to Grace (Tulp) Thorsheim and Archie Thorsheim. Having lost his father in an accident at the age of 16, Duane grew up quickly. Nicknamed "Lefty," he attended Austin High School, where he played varsity football for the Packers. Prior to graduation day in 1951, Duane enlisted at 17 in the United States Air Force and completed basic training in Biloxi, Mississippi. While stationed in France during the Korean War, his frame grew to 6'3" and 250 lbs., making him a valuable lineman for his U.S. Air Force Europe (USAFE) football team. Upon his discharge, he attended the University of Minnesota. Using experience gained from the Air Force in early mainframe computers, Duane secured a job at Cargill in Minneapolis. While based in the Midwest, he married and had two sons, Christopher and Mark, with his former wife, Susan (Soldin) Thorsheim. Duane and his family lived in Minneapolis and St. Paul, Minnesota, as well as in Des Plaines and Sherman, Illinois. They moved to Marlboro, New Jersey, in 1972, when he joined the Systems & Data Processing team at JCPenney's then headquarters in New York City. In addition to establishing a successful career in IT systems project management, Duane followed his sons' passion for soccer, and he channeled his (sometimes vocal) frustration with youth referees into becoming a licensed and respected official for youth soccer in New Jersey. In 1985, Duane married Susan (Sue) Dunzelman, who worked as an officer for J.P. Morgan. Upon both of their retirements, they moved to Philipsburg, Montana, in 2004, followed by Stevensville, Montana, in 2017, where they relished living among a kind community in the beauty of the Bitterroot Valley. He maintained a lasting relationship with his Austin High classmates, enjoyed playing bridge with local friends, and was still hitting the gym for workouts at the age of 90. He and Sue were especially grateful that his entire family gathered in Montana for a joyful celebration of his 90th birthday in September 2023. Duane is survived by his wife, Sue, his son Mark, and wife, Margot, of New Canaan, Connecticut, and their children, Max and Ben, along with Christopher's wife, Lori, of Manalapan, New Jersey, and their children Chelsea, Chris, Jen and Matt. Duane was pre deceased by his first wife; his eldest son, Christopher; his parents; and his siblings, Virginia (Thorsheim) Gill and Dennis Thorsheim. We mourn the loss of our husband, father, father-in-law, grandfather, soon-to-be great grandfather, and friend. But we will revel in the memory of his full and rewarding life.
