Florian was born February 9, 1932, the son of Felix and Victoria Ratajczak Sieracki. Florian graduated from Lincoln High School of Manitowoc in 1950. He served in the U.S. Navy from 1951-1955. He was an electrician on the USS Passumpsic (A0-107), a fleet tanker that operated from Sasebo, Japan to the Korean waters during the Korean War. After his military service he attended Stevens Point College and received a degree in education in 1960. Florian began his teaching career in Beaver Dam, WI, and taught 6th grade in the public school system. On June 24, 1961 he married Mary Ann Michel at St. Boniface Catholic Church in Manitowoc. Florian earned his master’s degree in administration at UW Madison and later moved to Waupun where he taught at Waupun Correctional Institution until his retirement in 1993. He was an avid gardener and enjoyed traveling, fishing, hunting, biking, and hiking. He also loved tinkering on never-ending projects in his basement and garage.

Florian is survived by Mary Ann, his wife of 58 years; three children: John (Cynthia) Sieracki of Appleton, Laurie (John) Fitzpatrick of Oshkosh, and Michael (Hazel) Sieracki of Spencer; 11 grandchildren: Joe (Lauren) Fitzpatrick, Nick (Foua) Fitzpatrick, Meaghan (Kyle) Retzlaff, Bill and Tim Fitzpatrick, Amanda and Adam (Kori) Fuerst, Anna and Thomas Sieracki, and Leigh Anne and Andrew Sieracki; 5 great-grandchildren: Sean, Conor, Rory, Genevieve, Gracie, and one more due in October; a brother, Lee (Heather) Sieracki; a sister, LuAnn (Don) Haupt; and many nieces and nephews.

Florian was preceded in death by his parents; his brother, Eugene Sieracki; and his sisters, Marian Osieczanek and Vicki Lachowicz.

Dad was a kind and gentle man. He was a proud veteran serving our country during the Korean War. He loved being outdoors with nature, and knew many plant and animal species. Dad was knowledgeable on many subjects and was the one to go to with our various questions. We will all miss our great conversations and talks with you. We love you Dad!


There will be a private funeral service for Florian Sieracki at Werner-Harmsen Funeral Home in Waupun with Rev. John J. Radetski of St. Joseph’s Catholic Church in Waupun officiating.

    I was sorry to hear about Mr. Sieracki. He was my 6th grade teacher at Washington Elementary. I think it was the last year he was there. I remember him as a patient teacher, and I unfortunately at the time, was one of those students who tried his patience on a regular basis. I’m guessing he would have been surprised to learn that I am a teacher. He was a good man and my condolences to your family.
