Andrew J. Rosenthal, age 61, of Hudson, Wis (formerly of Sheboygan, Wis.), passed away peacefully surrounded by his loving family on October 30, 2022, after a courageous battle with Parkinson’s.

Andy was born on September 19, 1961, to Norman and Marion (Schoening) Rosenthal in Sheboygan, Wis. He attended Holy Name School and North High School in Sheboygan and graduated in the class of 1980. Growing up the youngest of seven children, he learned to be independent and developed his sense of humor early on. Andy loved life and was happy.   Following his high school graduation, Andy went on to college at the University of Wisconsin-Madison where he graduated in 1985 with a bachelor’s degree in electrical engineering.

Andy was previously married, and was blessed with two children, Daniel and Anna, whom he loved dearly. Years later, he met and married his beloved wife Cathy on September 10th, 2016. Both Andy and Cathy had many things in common that brought them together, including graduating from the University of Wisconsin-Madison the same year, and their love of sports and family.

Andy was an electrical engineer and worked in the water filtration industry. He worked for many different businesses, including U.S. Filter, Siemens Water Technologies, Cummins Power Generation, and Telemetry & Process Controls. He enjoyed leading and managing people and took pride in his career.

Andy often joined his son Dan and his scout troop on camping trips and activities. He enjoyed being in the outdoors with his family and father-son trips to the BWCA during the summer for several years. Also, he supported Dan in Boy Scouts and helped him achieve his Eagle Scout.

Andy was a humble man; he’d be the one in the background helping and cheering on others with a smile. What drew people to him was his humor. If you spoke with him for a few moments, you would more than likely walk away laughing.  Andy was an avid Wisconsin Badger and Vikings football fan. You’d find him on the weekends watching both teams, with chicken tenders from Dairy Queen and a banana split blizzard. He had an infectious laugh and was taken too soon. He will be deeply missed by all who knew him.

Andy is survived by his wife, Cathy White; his children, Daniel and Anna Rosenthal; stepchildren, John and Kelsey Sigvertsen; his siblings, Loren (Susan) Rosenthal, Edith Sagal, Jane (Mike) Pratt, Keith (Donna) Rosenthal, Bruce Rosenthal, Lois (Jon) Seitenzahl, along with many other nieces, nephews, cousins, and close friends.  He is preceded in death by his parents, Norman and Marion Rosenthal; nephews, Adam Seitenzahl and Andrew Nelson. Also, preceded in death by Jack White, Cathy’s father.

A memorial service will be held at 11:00am on Friday, November 18, 2022, at St Patrick’s Church, 1500 Vine St, Hudson, Wis. with a visitation being held 1 hour prior to the service at the church. The service will be livestreamed on the church’s Facebook page. Interment will take place at a later date. Services are entrusted to O’Connell Family Funeral Homes and Cremation Services, 520 South 11th Street, Hudson, WI, 715-386-3725,

A memorial in Andy’s name can be given to the Parkinson Foundation:

  1. My thoughts and prayers to all of you, Andy brought joy to all those who knew him he will be dearly missed

  2. I met Andy at school in 1976-77. He was a great guy and funny right from the start! I remember him making up his own parodies of popular songs of the day, I wish I could remember them now! I hadn’t seen him in 20 years, but my memories of him will always remain fond. My condolences to his family.

  3. I was in gym class with Andy. At North back in the day you were encouraged to get a PE shirt, blue on one side, red on the other. We were juniors and during a flag football game, Andy’s shirt was torn when somebody missed the flag. Wasn’t a big tear, but enough to expose the red underneath and it looked kind of tough. That was the day Andy and I started “The Brandos”. If you made a good play, if you did something extraordinary, a great catch, you would earn a ceremonial tear in your PE shirt and become a member of “The Brandos”. By the end of the semester we had a group with shirts so torn up, some of us had to get new ones. Andy had a great sense of humor and was fun to be around.

  4. I only knew Andy for two years when he and Cathy moved to Hudson, Wisconsin. I enjoyed trying new restaurants with them both. He was a joy to be with and will truly be missed.
    Memory Eternal
    Andy is now asleep with the angels.

  5. For many, Andy was a calming presence in the midst of conflict. He wouldn’t let adversity get the best of him, and managed to maintain hope for future reconciliations. Although his sense of humor was rare, infectious and very much appreciated, he also knew how and when to take matters seriously. Many could count on Andy as a true and loyal friend. He will be missed, but certainly this is not the end for Andy, as we will all see him again someday.
