Brian Urquhart, who was Ralph Bunche's chief assistant from 1954 until Bunche's death in 1971, succeeded him as United Nations Under-Secretary-General for Special Political affairs -- a position created for Bunche by U.N. Secretary-General Dag Hammarskjöld in 1953. Some years ago, Urquhart published a fine and rich biography of Hammarskjöld. He has now given us a sensitive, informative, comprehensive, and often heartbreaking biography of Bunche: a great book about a great man.
