Acheson is the first complete biography of the most important and controversial secretary of state of the twentieth century. More than any other of the renowned Wise Men who together proposed our vision of the world in the aftermath of World War II, Dean Acheson was the quintessential man of action.Drawing on Acheson family diaries and letters as well as recent revelations from Russian and Chinese archives, historian James Chace traces Acheson's remarkable life, from his days as a schoolboy at Groton and his carefree life at Yale to his work for President Franklin Roosevelt on international financial policy and his unique partnership with President Truman.Chace corrects many misconceptions about Acheson's role in the Cold War. Acheson was not one of the original Cold Warriors. In 1945, willing to acknowledge Soviet concerns about its security, Acheson worked closely with Secretary of War Henry Stimson on a plan to share America's scientific information about atomic energy with Moscow in order to avert an arms race. It was only when Moscow made threatening demands on Turkey for bases in the Dardanelles that Acheson hardened his views toward the Soviet Union.Later, Acheson encouraged President Kennedy to stand firm against the Soviets in the Berlin Wall and Cuban missile crises. He headed a group of elder statesmen who advised President Johnson on the Vietnam War. When Acheson turned against the war, Johnson realized that domestic support for his policy had crumbled.
