Robert Gruetzmacher, Chief Warrant Officer Four (Ret.), age 90, formerly of Merrill, passed away on December 26, 2019, in Sun Prairie.
He was born on December 17, 1929, the son of George and Edna (Kuether). As a youth he was a Boy Scout, and worked in the family School Supply Store. After graduating from Lincoln high school, he was a photographer, a Radio and TV repairman, and a Broadcast Radio Engineer for WOSA & WLIN. In 1950 he entered military service with the Wisconsin National Guard, starting as a Tank-Turret Radio Mechanic.

When the Nike Sites were phased out he went to work in the Technician (Civilian) Personnel Office of the Wisconsin Guard in Madison, retiring in 1989. In retirement, he worked in the archives office at the United Methodist Conference Center in Sun Prairie, and spent many hours with his wife exploring family genealogy.
