Delano Jay Sylvester, of Lake Saint Louis, Missouri, passed away Thursday, March 28, 2025, at the age of 90. Beloved husband of the late Martha Louise Sylvester; cherished son of the late Jay Merle and Lelia Ella Sylvester; devoted father of Elizabeth A. Sylvester, William J. (Cynthia) Sylvester, Robert A. (Donna) Sylvester, and Scott E. (Erin) Sylvester; loving grandfather to 10 grandchildren and 12 great grandchildren.

Delano came from humble beginnings and dedicated his life to improving himself in every way he could. He honorably served in the United States Air Force for 25 years, assigned to 7 locations across the United States, Europe and Asia. He was awarded a Master’s Degree in in Electrical Engineering from MIT. Later as a program manager at McDonnell Douglas/Boeing, he was deeply committed to his work, particularly enjoying the cutting edge technology, travel and competitive nature of his work.

Through his determination, hard work and intelligence he built a successful life for himself and provided well for his family. A semi-pro bowler and a Life Master bridge player, Del was fiercely competitive. He had a gentle side however, building strong bonds with his Rottweiler’s and having the right touch to help feral cats learn to trust and feel safe. A self-made man, Delano created a successful life for himself through sheer will and perseverance, leaving a legacy of hard work and excellence. He was dearly loved and will be greatly missed by all who knew him.

Memorials may be made in Delano's name to the American Heart Association.
