He also enjoyed volunteering at Hagley Museum and Library in Wilmington, Delaware. As a magician Bill found excitement in entertaining audiences of all ages. Other interests include writing a children’s book about Amateur Radio, sailing and inventing. He holds two U.S. Patents, including a novel idea to silence jet engines (PN 5,488,666 A system for suppressing sound from a flame). He also loved history and genealogy. After extensive research, he was inducted into the Sons of the American Revolution (SAR) along with his sons and grandsons.
