Jon Philip Molzahn

November 26, 2021 | 8 comments

Jon Philip Molzahn, aged 77, died November 20, 2021. He was born in La Crosse on June 19, 1944, to Harold C. Molzahn and Lillian (Norem) Molzahn..

Jon was diagnosed with Type I Diabetes at the age of 19 and wore an insulin pump, as soon as they became available, for many years.

Jon was a registered architect, working with his dad and Carl Schubert in the architectural and engineering business. He spent his last few years prior to retirement as a building plan reviewer for the State of Wisconsin.

He was a life-long member of First Evangelical Lutheran Church in La Crosse, Wisconsin.

He had a passion for (and was owner of) many cars, especially Corvettes and the Buick Gran Sport. He loved to spend his spare time going for drives in his convertibles, or fixing and cleaning them up. He treasured his time as a member of the local Corvette Club, and the time spent with the friends he met there..

He also had a life-long interest  and pride in his family history and the architectural history of the La Crosse area. His father, Harold, and his grandfather, Theodore J. Molzahn, had a construction and engineering business (T. J. Molzahn & Sons Construction). Some of the projects they built were the original Pettibone Beach bathhouse and the original Riverside Park bandshell.

Jon is survived by his wife of 54 years, Judith (Sullivan) Molzahn, daughter Jennifer (Patrick) Oldenburg, son, Jonah (Sarah) Molzahn, grand-daughter,  Lillian (Lilley) Oldenburg, – beloved dog, Daisy-, and his best friends, Doug Willer and Bob Willer.

Brothers Harold Jr., Paul, Grant,  and sister Marion preceded him in death.

A special thank you to Dr. Thomas Cunningham (and Maggie), and Dr. Jane Korducki of Mayo Clinic in La Crosse.

Private church services will be scheduled in the spring.

      Dear Judy, I am so sorry to hear of Jon’s passing. 54 years of marriage is a remarkable feat. You were blessed to have each other for so long, but not long enough. May you be rewarded with many good memories and blessings.
      Sincerely, Carlyn (Halverson) Ellis

    Judy, so very sorry to hear of the passing of Jon. My husband passed away two years ago and Greg Tanke, last year.

    You will find as we have, it isn’t easy.

    Please know I am thinking of you and your family. Oh, the fun we all had together in the Corvette Club. Fond memories.

    Sincere condolences.

    Sorry to hear of Jon’s passing. I worked with him for many years while he was a building plan reviewer for Wisconsin. I enjoyed his sense of humor and our many conversations ranging from sports to autos. His love of history was obvious and especially fun as he shared his knowledge of the significance of local buildings. Our condolences to you and your family Judi.

We are sending thoughts and prayers to you and your family, Judith. Take care-
