Ken Charles Siewert

Kenneth Charles Siewert, 82, of Wausau, passed away peacefully on Aug. 13, 2025, surrounded by his family after a brief illness.

Ken was born Sept. 10, 1942, in Wausau to Arthur and Agnes Siewert. He graduated from Wausau High School and retired at age 60 as a design engineer at Wausau Metals.

On Feb. 8, 1964, Ken married Alice F. Smith. The couple shared 61 inseparable years together, raising three children and building a life filled with love and devotion. He especially enjoyed walking with Alice at Marathon Park, where he continued his regular strolls until just weeks before his passing.

Ken was a devoted sports fan who rarely missed a Milwaukee Brewers game or a Sunday cheering for the Green Bay Packers, where he was a season ticket holder. He also enjoyed bowling, woodworking and helping with projects for his family. He was also a longtime member of St. Mark’s Lutheran Church in Wausau.

Survivors include his wife, Alice; their children Darren (Shereen) Siewert, Jennifer (Todd) Schueller, and Kurt (Erin Umlauft) Siewert; grandchildren Paige (John), Megan (Danny), David, Kayla (Collin), Kaylie, Addyson, Isla, Livvy, Maisie, Brynlee, Devon (Linda) and Rowan; and great-grandchildren Maiya, Arie and Franklin. He is further survived by his brother-inlaws Robert Smith and Frank Radigan; sisters-in-law Barbara Hartwig and Diane (Arlow Erickson) Smith; and many nieces, nephews and friends.

He was preceded in death by his parents and his brothers, Richard “Dick” Siewert and David Siewert.

A private family celebration of life will be held at a later date. Ken will be laid to rest at Restlawn Cemetery in Wausau. Helke Funeral Home is assisting the family with arrangements.
