Fredrick "Fred" W. Mattheis Sr.

Fredrick “Fred” William Mattheis Sr., age 88, from Rosendale, Wisconsin, peacefully joined his loving Savior, surrounded by loved ones on his family farm, on January 9th, 2025. Fred was born on April 8, 1936, in Oshkosh, Wisconsin, to Bernard and Maisie (Gardner) Mattheis. After graduating from Rosendale High School, he married Sally Kemnitz on March 6, 1955. Fred and Sally laid their roots in Rosendale, Wisconsin, raised three children, and shared 48 wonderful years together before her passing on February 4, 2004. Fred loved working with automobiles and made his career as a mechanic at O.R. Bluemke’s, owning his own service station, teaching at Moraine Park, and lastly working as an Insurance Adjuster. Fred dedicated himself to family and community. He served in the Rosendale Fire Department for over 50 years as a firefighter, Fire Chief, and secretary. He was an avid long-time scouter and mentor. Fred joined scouting in 1951 at the age of 15 and earned his Eagle Scout in 1957 at the age of 21. He volunteered with Troop 734 in Rosendale for nearly 60 years, serving as Scoutmaster for 43 years. Most of all, Fred loved spending time with his family, grandchildren, and animals. His perfect day would be spent at the pond watching the children fish and play while the adults reminisced around the campfire making s'mores. This legacy will carry on for many generations. Fred also devoted his time to several organizations, including the Mid-America Geographic Foundation, Rosendale Historical Society, Rock River Archaeological Society, teaching hunter safety through the DNR, and the Fox Valley Stock Car Club, where his car Snoopy A11 won the points championship in 1972.
