This is a one-volume biography of one of the greatest presidents and world leaders of the 20th century. Drawing upon extensive sources and recent scholarship, it examines the moulding and maturing of the complex inner man and the dynamic, charming public figure. The focus is upon Roosevelt's often controversial ideas and actions as he undertook through the New Deal to modernize the nation, and during World War II to take the lead in establishing a secure world order. The portrait that emerges is of a president possessed of superb political instincts surprisingly mainstream in his political beliefs.
