Mr. Robert Mueller of Fredonia passed away at his home early Thursday morning, October 19, 2017, while surrounded by the love of his family. He was 81 years old. Robert was born in Saukville on September 25, 1936, son of John P. and Ruth Vetter Albinger Mueller. On May 10, 1958 he was united in marriage with Carol Barwick at St. Mary's Catholic Church in Port Washington. The couple settled in Port Washington, but moved to Saukville, Random Lake and later to Fredonia. Mr. Mueller was a national barefoot waterskiing champion and holds current records for the Senior Men's Division. He competed for over 20 years and was still skiing well into his 70's. For years, after coming home from work as a maintenance electrician at Tecumseh Power Products in Grafton, Bob could be found barefoot skiing on Random Lake, with his wife driving the boat and his son spotting. He was also an avid tennis player and at one time had even built a tennis court at their home outside of Saukville. Bob enjoyed watching local sports teams, hunting, and camping with his family. He played an integral part in the lives of his children and grandchildren, and was always there to cheer them on. Survivors include his wife Carol of Fredonia, their children Patricia Penkwitz of Grafton and Robert J. (Kim) Mueller, Jr. of Port Washington, five grandchildren: Katherine Penkwitz (fiancé Jason Canora) of Sheboygan, Christopher Penkwitz (fiancée Rachel Staton) of Saukville, Rob Mueller of Grafton, Ryan and Johanna Mueller, both of Port Washington, and great-grandson Dominic Canora.

He is preceded in death by daughter Christine Ann Mueller and four brothers: Reggie (the late Frieda), Nick (the late Mae), John (the late Billie) and Eugene (the late Sharon).
