William "Bill" Joseph Momeno

William "Bill"  Momeno, of O’Fallon, MO, passed away Tuesday, July 8, 2025, at the age of 89. Beloved husband of Vivian J. Momeno; cherished son of the late Marion and Joseph Momeno; devoted father of Michael (Valerie) Momeno, Kathy (Rob) Lenahan, and the late Debra Phillips; loving grandfather of Jordan Momeno, Kennadyn Momeno, Caleb Lenahan, Ashley Lenahan, Emily Phillips, and Zoie Phillips.

William was married to the love of his life, Vivian, for 60 wonderful years, and together they shared a passion for league bowling, square dancing, and traveling. A talented aircraft engineer at McDonnell Douglas for nearly 30 years, William took great pride in his work, especially his favorite aircraft, the F-15. He loved the outdoors and had a knack for fixing and tinkering, particularly with cars. A devoted Cardinals baseball fan, he also had a deep interest in science, math, and history. William was remarkably self-taught and could accomplish anything he set his mind to. He was dearly loved and will be greatly missed by all who knew him.

Memorials may be made in William's name to the Parkinson’s Foundation.
