John "Jack"

Spengler

John (Jack) Spengler, age 80, of Boynton Beach, FL, passed away on October 21, 2026, leaving behind a lifetime of laughter, unforgettable stories, and memories that will continue to bring smiles to those who knew and loved him.

Born on January 6, 1946, in Rock Island, IL to the late Virgil and Delores Lorraine Spengler. Jack graduated from Sherrard High School and proudly served his county in the United States Navy Reserves. He retired from Walmart Corp.

A lifelong learner, Jack was always interested in discovering something new. One of his most unique accomplishments was working with a university to discover and name several fossils, now housed at the Smithsonian – proof that his curiosity could lead to some pretty remarkable places. He loved photography and had a lifelong love of animals, even owning and operating a pet store in his younger years.

Jack was previously married to Joyce (Kistler) Spengler. Although their marriage ended in divorce, their friendship never did. They remained the best of friends until her passing, sharing a special bond that stood the test of time.

He was preceded in death by his parents, Virgil and Lorraine Spengler; his two brothers, Larry Spengler and Thomas Spengler; and his former wife and lifelong friend, Joyce Spengler.

He is survived by his sister, Jan (Gary) Dochterman, sisters-in-law, Cheryl Spengler and Janet Spengler, and many nieces and nephews who will forever cherish the memories they made together.

Graveside services will be held on Saturday, November 21st at 10:00 AM at the Buffalo Prairie, IL Cemetery. Wheelan-Pressly Funeral Home and Crematory, Milan is assisting the family.
