Zimmer, Dennis Norbert age 84 of Bloomington, MN and Sun Lakes, AZ passed away July 22, 2020. A graduate of St. Johns University, Dennis was a US Army Colonel serving in the Reserves for 35 years. When he wasn't out leading the charge in war games, he was one of the all-time great Rube Goldberg "home improvement" guys of his day. If there ever is a hall of fame of home hackers, he should be inducted on the first ballot. We'll think of you every time the lights flicker dad, love you. Preceded in death by his parents, loving wife, Charlotte; brothers, Donald and Daryl; and granddaughter, Jennifer. Survived by children, Debra (Daniel), Kevin (Leanne) and Lisa (Todd); sisters, Valaria and Joan; and 10 beautiful grandchildren.
