Peter Goodchild demonstrates in this sensitive and fascinating biography [that] Teller’s danger arose from the fact that he was both a brilliant scientist and a skilled political manipulator—but unfortunately also a man of limited wisdom. It would be easy to ridicule [Teller], but Goodchild, to his credit, resists shallow scorn. Teller emerges as a complicated individual whose actions were always logical, if rather warped. He becomes rather more frightening than I had ever previously imagined, for it is no longer possible to dismiss him as a madman.
