After retirement from baseball Kuhn worked for various companies, including Kentucky Fried Chicken, Mister Donut and Children's Discovery Centers. In 1999 he moved to Truckee, California and worked at a Lake Tahoe resort. He died at the age of 73 in Layton, Utah and survived by wife Peggy and children Carrie, Amy, Scott and Stan. Kuhn was a four-sport star (baseball, football, basketball, and track) at Male High School, noted in 1955 (before Muhammad Ali), as "possibly the greatest all-around athlete ever to come out of Louisville."
