Bill was a devoted husband and father. He was active in civic organizations and Catholic parishes wherever he lived. He was a Fourth Degree member of the Knights of Columbus. Bill was a sports fan, beginning as a boy in Fort Wayne when he listened to Chicago Cubs games on the radio. He always enjoyed watching baseball and basketball and he played tennis in younger years. He enjoyed all kinds of games and played bridge with Mary and their friends for many years. He enjoyed taking his sons fishing and playing ball with them.

Bill appreciated music and often attended classical concerts and jazz music events. He read a lot and had a passion for stories about sports, historical novels, espionage classics and mysteries. Bill loved mountain hiking and took his family on several summer trips to the Rocky Mountains in Colorado. He also enjoyed visiting his wife's relatives in Arkansas and took the family to Conway for many summer vacations. He and Mary enjoyed retirement years in Ann Arbor, Sun Lakes, Arizona and Novato, California.

He lived by the highest Christian norms and left us with the eternal values of fidelity, gratitude and honesty. His example imbued in his children a natural desire to leave the world a better place.
