John Michael Doe, age 76, passed away peacefully at his home on July 10, 2025, surrounded by loved ones. Born on March 3, 1949, in Cedar Rapids, Iowa, John was a devoted husband, father, grandfather, and friend. A graduate of the University of Iowa, John spent over three decades as a high school history teacher, known for his passion for storytelling and his dedication to every student who walked through his classroom door. He believed deeply in the power of education and was a mentor to many throughout his career. John married his high school sweetheart, Mary, in 1971. Together they built a life full of laughter, love, and adventure, raising two children and later welcoming four grandchildren, who brought him endless joy. In retirement, John could often be found working in his garden, cheering on the Hawkeyes, or sharing coffee and stories with friends at the local diner. He had a quick wit, a generous spirit, and a heart that made room for everyone. He is survived by his wife Mary, his children Sarah and David, and his grandchildren Emma, Jack, Lily, and Ben. A celebration of life will be held Saturday, July 19, at 11 a.m. at Grace Lutheran Church in Cedar Rapids.
