(Tribune News Service) He was a community leader supporting local performing arts, a renaissance man, a dapper dresser and a fun guy with a quirky sense of humor. Friends and colleagues were remembering philanthropist William J. Gillespie who died of natural causes on Thursday, Dec. 10. A Laguna Beach resident, he was 79. He had quite a diverse background, said John Gunnin, a board member of the William Gillespie Foundation. He was a Marine, and then of course he was a guy from theater, ballet, dance, he had all of these loves, and he was very generous to all of these different Orange County organizations. He had a wonderful sense of humor, very unexpected, and he really marched to his own drum, Gunnin said.
