Ed found joy and contentment in retirement by working on various gardening, landscaping and farm projects with his loving wife, Debra Tiedemann, whom he married on July 14, 2012. His sanctuary was the family farm in St. Clair County, Illinois where he and his family created enduring memories. He never let a day go by without solving several Sudoku puzzles.
