Who's Who Writer CYNTHIA HAVEN seemed ideal to tackle the many lives of Dana Gioia, since she's worn so many hats herself. A freelance literary critic for the San Francisco Chronicle, Haven has covered poetry, opera and theater for newspapers and magazines throughout the United States and in Britain. While she was news director at the School of Education, she co-authored two books on learning. More recently, she has seen her own poetry published. "As a journalist, I became convinced that someone needed to describe the contemporary scene in language that would reach the kind of audience that used to be interested in poetry half a century ago," she says. "We are all shareholders in poetry."
