Charles Freund Rietz passed away peacefully at home in Wausau, Wis., on Dec. 29, 2019.

He was born in Chicago, Ill., on Aug. 22, 1920, to Walter and Margaret Rietz, so he was mere months away from celebrating his 100th birthday.

Chuck was a wonderful father, brother and grandfather and will be missed.

Chuck grew up with his two younger brothers in Highland Park (Ravinia), Ill. 

After attending school in Highland Park/Ravinia, Chuck attended Purdue University attaining his mechanical engineering degree.

After graduation Chuck went to work in Milwaukee as an engineer with Allis Chalmers Corp. 

In 1944, Chuck enlisted in the U.S. Navy. He began as an engineering officer of a ship, then executive officer and finally captain of his ship, traveling through much of the Pacific.

When Chuck returned from Naval service, he went to work for ILG Industries, an industrial ventilation company in Chicago, working his way up through the ranks to chairman of the company. He worked for ILG for the remainder of his career until his retirement.

In 1947 Chuck married Dorothea Lillian Boehm.  They had four children.  “Dot” passed away in 1995.

Chuck married Mary Schaeffler on Nov. 27, 1997.  Dad and Mary had 21 years together before her passing in 2018.

He was a pilot, a car enthusiast, enjoyed many outdoor activities and always endeavored to do his best.

The family wishes to thank Dad’s extraordinary caregivers — Cindy, Nancy and Linda.  They are angels on Earth. 

Chuck is survived by his brothers, Walter and Robert; and sister-in-law, Nancy;  his children, Peter (Kathleen), Tom (Darcy) and Shelley; his grandchildren, Amanda, Brandon, Benjamin, Chad, Casey, David, Spencer, Jennifer, Thomas and Henry; and eight great-grandchildren as well as Mary’s children, Kathy, Tom (Mary), Lis (Bill), Bill (Gail), Ann (John), Judy (Gene), and Bob (Deedee); and Mary’s nine grandchildren. 

A service to be held in Three Lakes, Wis., will be announced at a later date.
