James William Amstadt

James “Jim” William Amstadt, 91, of Traverse City, passed away peacefully on September 21, 2025, surrounded by his loving family. Born on March 21, 1934, in Milwaukee, Wisconsin, Jim was the son of the late Frank Anton and Harriet Ruth (Lemanczyk) Amstadt. He graduated from Marquette University and went on to enjoy a distinguished 35-year career with General Motors, retiring in 1991. On August 14, 1953, Jim married the love of his life, Roberta Mary Behm. Together they shared 72 wonderful years of marriage and raised a beautiful family filled with love, laughter, and lifelong memories. Jim had a passion for learning and a deep sense of curiosity that fueled his love of travel. Throughout his life, he visited 58 countries, with cherished trips to Scotland, South Africa, and Egypt. It was during his business trips to Scotland that he discovered his lasting appreciation for Scotch whisky. Jim gave generously of his time to his community, serving as a proud member of the Knights of Columbus, where he served as Grand Knight for five years. Jim also served as the President of his neighborhood condo association for 10 years and as a longtime Little League umpire. He also developed and mentored the local youth umpire program. In his younger days, Jim was known to delight friends and family with his accordion playing. A dedicated engineer, Jim was part of the guidance systems department that supported the historic Apollo space missions. His contributions were so significant that his name is commemorated on the moon. He is survived by his beloved wife, Roberta, and their children: James Amstadt, Robert Amstadt, Mary (John) Kelsey, Kristine (Robert) Holder, Steven (Jaime) Amstadt, and Susan (Rodney) Prater. He also leaves behind 15 grandchildren: Joseph, Robert, John, Samantha, Amanda, Ashley, Coryell, Allison, Michael, Alex, Nicholas, Tate, Tobyn, Teagan, Chelsea, and Stefanie; 16 great-grandchildren; and his brother-in-law, Alex (Nancy) Behm. A Memorial Mass will be celebrated on Friday, September 26, 2025, at 11:00 a.m. at St. Joseph Catholic Church, with visitation beginning at 10:30 a.m. A luncheon will follow at Sleder’s Family Tavern. In lieu of flowers, memorial contributions may be made to the Grand Traverse Regional Land Conservancy, an organization close to Jim’s heart.
