Passed away peacefully on Monday, December 11, 2023, at the age of 89 with family by his side. Beloved husband of the late Carol (nee Manteufel). Loving dad of Scott (Debbie) Thiermann, Tyrone Thiermann, Kim Thiermann, Todd (Barb) Thiermann, Jodi (Ken Baginski) Wire, and Joan Gilson; his grandchildren Shane (DaCarla Wilson) Thiermann, Lisa Beekman, Carrie (Rob "Oz" Osborne) Thiermann, Amanda (Tommy) Pearce, Josh (Kristen) Thiermann, Jake (Tessa) Thiermann, Alex (the late Philip) Coss, and Sophia Gilson; his great-grandchildren, Emily, Lexi, Max, Atlas, Brinley and Gabriel. Preceded in death by his grandson Jack Scott Gilson.

Eugene was a proud Coast Guard veteran who served in the Korean War and was grateful to be part of an Honor Flight with fellow veterans. He loved his cottage in Hayward, fishing on the Chippewa Flowage, playing the accordion and telling a good joke.

He spent his final days in the care of outstanding staff at Grafton Aurora Hospital and his final hours at Zilber Hospice, surrounded by loving family. Heartfelt thanks to Lisa, Alyson and the staff at Teal Shores for providing such great friendship, care and comfort to our Dad. Special thank you to Patsy and Ben, palliative care angels, who offered peace and guidance to Dad and family during Dad's final days.
