Philip E. Ginsburg enjoyed several careers, sacrificing the advantages of continuity and seniority for the pleasures of new challenges and a variety of experience and learning. The common thread was writing, and each profession fed his curiosity about individual lives and how they fit together in a mosaic of politics and culture. Ginsburg started writing before he was a teenager as a reporter for a short-lived summer camp newspaper. After college and a term in the Peace Corps, he worked as a newspaper reporter, a college professor teaching comparative and Chinese politics, and executive director of the New Hampshire Humanities Council. On a sabbatical from the Council, he turned what was intended to be a magazine article harking back to his journalism days into a book, Poisoned Blood, which became a New York Times bestseller. His subsequent career as a freelance writer produced histories, brochures and other materials—mostly for nonprofit organizations—and a second true crime work, The Shadow of Death. Since retiring as a writer, Ginsburg has worked as a volunteer advisor/mediator at the New Hampshire Consumer Protection Bureau and a court guardian for children in abuse and neglect cases. He also served in the New Hampshire House of Representatives.
