Franklin Delano Roosevelt stands astride American history like a colossus, having pulled the nation out of the Great Depression and led it to victory in the Second World War. Elected to four terms as president, he transformed an inward-looking country into the greatest superpower the world had ever known. Only Abraham Lincoln did more to save America from destruction. But FDR is such a large figure that historians tend to take him as part of the landscape, focusing on smaller aspects of his achievements or carping about where he ought to have done things differently. Few have tried to assess the totality of FDR's life and career. Conrad Black rises to the challenge. In this magisterial biography, Black makes the case that FDR was the most important person of the twentieth century, transforming his nation and the world through his unparalleled skill as a domestic politician, war leader, strategist, and global visionary--all of which he accomplished despite a physical infirmity that could easily have ended his public life at age thirty-nine. Black also takes on the great critics of FDR, especially those who accuse him of betraying the West at Yalta. Black opens a new chapter in our understanding of this great man, whose example is even more inspiring as a new generation embarks on its own rendezvous with destiny.
