Kratsch, Don Henry age 75, of Centerville and Three Lakes, WI, took his final flight on October 15. Survived by wife Sue, sons Charlie (Brenda) and Rob, daughter Cyndi (Tony) Pasma, and 7 grandchildren. Don was born in Oshkosh, WI, on 24 April 1942. He spent summers on the water, canoeing, sailing, and water-skiing. He attended Oberlin College and graduated from the University of Colorado, becoming a flight instructor and later earning a floatplane rating. At West Publishing and later at American Express Financial Advisors, he was responsible for the acquisition of mainframe computer hardware; his skill in principled negotiation won him friends throughout the industry. After retirement he worked with son Charlie in founding the Infinite Campus software company, where he served as CFO and Director. Don loved nature, the woods, and caring for his land and cabin near Three Lakes. In 1983 Don, with help from family, hand-planted 10,000 Norway pines on his property, established a tree farm, and became Tree Farmer of the Year for Oneida County. Two conservation easements on the property are held by the Northwoods Land Trust. Memorials to Northwoods Land Trust, 519 E. Wall St., Eagle River, WI 54521, or to any environmental organization.
