William Alan (Bill) DuParri Sr., age 79, of Ballwin, Missouri passed away peacefully at home on February 15, 2026.

Bill was born February 21,1946 in Manchester, Missouri to Otto and Charlotte (nee Feldmann) DuParri. He graduated from Parkway High School in 1964 and was employed with Southwestern Bell Telephone for over 30 years.

Bill was married to Mary Julice DuParri (nee Kleba) for 54 years. He is survived by his wife, his sons, Bill DuParri Jr. (Leigh Ann), Chris DuParri (Alex Rich) and grandchildren Abby Marquis Quinn and Eli Alan DuParri. Though an only child, Bill had a large extended family of relatives and many close and loving friends.

Bill was an avid outdoorsman who spent time camping, fishing, hunting and exploring the woods and streams of Missouri with his family and friends. He was a car buff owning and restoring several classic vehicles over the years. Humor was a constant with Bill. He had a joke for every occasion, a rich treasury of stories and a collection of handmade quirky gadgets that were sometimes useful and often funny. Bill was happy to make your day a little brighter, a little funnier, a little lighter. He will be dearly missed.
