Franklin Delano Roosevelt: FDR, by Jean Edward SmithRead about the other entries on the list.
One of our greatest presidents deserves one of the greatest biographies ever written, and Smith comes through with her epic, well-written, and impeccably researched 2007 book. Smith offers a panoramic view of FDR, a man born into wealth and affluence who wound up a champion of the middle class and poor, a president whose efforts to guide the country out of the Depression were failures until World War II came along—and yet a man who is still routinely included in the top five presidents of all time.
