William Ollier

William L. Ollier, 82 of Mason passed away on November 25, 2025. Born to Eugene and Elva Ollier on December 28, 1942, in Cincinnati, Ohio.

A 1960 graduate of St Xavier High School and a 1965 graduate of the University of Cincinnati, where he earned a degree in electrical engineering. After serving in the US Air Force, Bill went on to spend 40 years in Dayton with NCR as a programmer, trainer and technical specifications writer following college.

Bill was a proud and dedicated veteran in the United States Air Force as a reliability officer, trainer, and expert in missals for over 11 years.

He enjoyed spending time in his yard during all seasons, but his favorite time was in the winter when he fed all the wildlife. The birds and squirrels that came to the window and the deer nestled in the woods. A true oasis of beauty and relaxation for him and Carol.

Bill and Carol traveled the world together. His passion for history, different cultures and visiting a new museum for hours is what he loved most about traveling. They cruised the beautiful Baltic Sea and flew to China, Russia, Mexico and in the Canadian mountains.

He had the patience and love for fishing, fine arts, especially Broadway and the quiet presence of his home. A life well lived.

Preceded in death by his parents, and his first wife and mother of his children, Dell Ollier.

Bill is survived by his wife, Carol Hauser, his children, Daniel Ollier, Joseph Ollier, Marcia Childs, Theresa Johnson and honorary daughter, Tawnya Wilson, his beloved grandchildren, Ashley Ollier, James (Kristen) Ollier, Mitchell Ollier, Emily Ollier, Nick (Sage) Childs, Natalie (Elijah) Erisman, Nathan Childs, Aleasha King, Darnell Lanier, Eli Wilson, Eva Wilson and Ethan Wilson, great grandchildren, Lily, Emma and Owen Ollier, Charlotte and Amelia Erisman, Lillith, Chloe and Evie King.
