John "Jack" A. Katzenberger, age 79, died June 30, 2022, at SSM Health Monroe Hospital. He was taken to his Heavenly home surrounded by his loving wife and two children. Jack was born on September 25, 1942, in Shannon, Illinois, to Arnold and Marlene Katzenberger as the third eldest of six kids.

He worked at the cob plant in Waddams Grove, IL, and ran his own trucking business shelling and hauling corn in his younger years. On June 22nd, 1963, he married Jean M. Olthoff at Wesley United Methodist Church in Stockton, IL, and raised two children in Waddams Grove. Anyone who knew Jack knew of his strong work ethic. He went on to work for Harbach Grain Farms with his passion for farming. After leaving Harbach Farms, he drove semi delivering dairy products into Chicago for Dean Foods and had a part-time gig welding for Dean Foods as well. He was hard-working and committed to providing for his family. He was also a member of the St. John's Lutheran Church.

When speaking with Jack, you were most likely talking about antique tractors or farming. Those were his other passions. He enjoyed going to threshing and farm shows, cutting wood, working on welding projects, collecting antique tractors, talking about crops, and enjoyed his dog, Mooshka.
