Michael Guy, of Random Lake, formerly of Fredonia, passed away peacefully at home surrounded by family, in the early morning hours of Wednesday, March 26, 2025. He was 86 years old.

Mike was born in Milwaukee on August 12, 1938, to John and Elsie (nee Holtz) Guy. Mike grew up in Milwaukee and was a proud graduate of Marquette University High School and the University of Wisconsin - Madison School of Pharmacy.

On July 27, 1963, he married Patricia Roncke at Blessed Sacrament Catholic Church in Milwaukee, and together they raised four daughters, affectionately known as "The Guy Girls."

A true innovator and entrepreneur, Mike had a diverse and fulfilling career. He taught high school chemistry, managed pharmaceutical manufacturing companies, and founded numerous businesses, including Guy Drug and Guy and O'Neill, both in Fredonia. Notably, Mike held several patents, including the original patent for time-release aspirin.

Mike enjoyed world travel, especially to Ireland and Las Vegas. He also loved fishing, singing old wartime songs with his daughters and grandkids, and playing the harmonica.

He is further survived by his brothers John (Margo) Guy and Patrick (Anne) Guy, other relatives and many, many friends.
