The story of Joseph Clark Grew (1880-1965) is the story of the modern American diplomatic tradition. Grew served the U.S. government for over forty years, with an impressive career that included two ambassadorships, two secretaryships, two ministerships, and every junior rank in the service. Grew was in Berlin when the U.S. went to war with Germany in 1917, was American Ambassador to Japan during the years leading up to Pearl Harbor, was Undersecretary of State during the war, and was instrumental in planning U.S. postwar strategy in the Far East. In this rich and intimate biography, Heinrichs draws on Grew's vast diary, correspondence, and several private and official collections to reconstruct the life of an extraordinary career diplomat. Here, Joseph C. Grew emerges as a man of peace who used both skill and insight to slow the world's progress toward World War II.
