Frank M. Johanek

October 26, 1948 ~ January 15, 2023 (age 74) 74 Years Old


Frank M. Johanek, age 74, passed away at Froedtert Hospital in Milwaukee, WI on January 15, 2023.  He fought hard for nearly two years but ultimately passed away during his battle with Leukemia.

Frank was the second son born to Alois Johanek and Helen (Chlopek) Johanek in Shawano, WI on October 26, 1948.  He spent his early years tending the family farm with his parents, brother, and sisters.  He loved repairing and maintaining farm machinery which eventually led him towards his career in engineering.  An inspiration from a classmate in a high school drafting course solidified his decision.

Frank attended Milwaukee School Of Engineering in Milwaukee, WI and received his bachelors degree in mechanical engineering.  He entered the Army Reserve after he completed his undergraduate studies which honed his focus, perseverance, and ability to work with a diverse culture of people.  He carried these learned values throughout his life.  After his service in the army he pursued a masters in mechanical engineering at Marquette University in Milwaukee, WI.

Frank married his wife and best friend Wendy in 1974.  In their 48 years of marriage, they were blessed with three sons: Benjamin, Nicholas, and Alexander.  He was a dedicated father and husband whose priority was to guide his family towards happiness, fulfillment, and success.  All three of his sons followed in his footsteps and also became engineers.  He was actively involved in the lives of his 4 grandchildren and it is debatable whether he or they enjoyed their time together more.

Frank spent the first half of his career at Milwaukee Boiler Manufacturing Company in Milwaukee, WI where he was employed as a mechanical engineer.  There he was instrumental in developing unique and customized solutions to engineering needs across many industries.  He worked to deactivate nerve gas bombs for the United States Government.  He helped to dig the largest tunnel in Seattle in 1983 through Mt. Baker Ridge into the downtown.  He developed a hyperbaric chamber for St. Luke’s hospital in Milwaukee, WI.

During the second half of his career, Frank worked with Federal Mfg Co. in Milwaukee, WI to build bottle filling machinery worldwide.  He enhanced his engineering skill set to include management, business development, and eventually ownership in the company.  Through his tenure, he developed positive relationships and gained profound respect from his coworkers.  He retired in 2014.

Frank left this earth too soon.  Spending time with family, participating in multiple sports (golf was his favorite), and relaxing at his retirement home in Naples, FL made him exceptionally happy.  He had many talents and enjoyed working side by side with family and friends on home improvement projects. With his high standards, he reached for the moon in everything he did.  He will be missed by many.

Frank was predeceased by his parents Alois and Helen Johanek as well as his older brother George Johanek. Frank is survived by his brother Al Johanek and sisters: Theresa Johanek, Marilyn Olson, Rose Mehlberg, Alice Vander Wyst, and Helen Pavalko.  

Frank’s wishes are to have a private funeral with immediate family members.  In remembrance of Frank and his efforts to fight leukemia, we ask that in lieu of flowers or gifts that donations be directed towards the Leukemia and Lymphoma Society (
