A bona-fide American hero at the close of World War II, General Dwight Eisenhower rode an enormous wave of popularity into the Oval Office seven years later. Though we may view the Eisenhower years through a hazy lens of 1950s nostalgia, historians consider his presidency one of the least successful.

Roosevelt's presidency was one of the most eventful in U.S. history. He took office in the midst of economic crisis: the stock market had crashed and millions of Americans were unemployed. He demonstrated an optimism and resolve that garnered quick support for his administration and for the programs that he called the New Deal. The first president truly to understand the power of the new mass media, Roosevelt rallied the nation through "fireside chats" on the radio and speeches on movie house newsreels.

As a general, Ulysses S. Grant is routinely described in glowing terms: the man who turned the tide of the Civil War, who accepted Lee's surrender at Appomattox; the man who had the stomach to see the war through to final victory. But his presidency is another matter. The most common word used to characterize it is "scandal."

Perhaps no U.S. president was less suited for the practice of politics than John Adams. A gifted philosopher who helped lead the movement for American independence from its inception, Adams was unprepared for the realities of party politics that had already begun to dominate the new country before Washington left office. But, as John Patrick Diggins shows, Adams's contributions still resonate today.

The dramatic, pulse-pounding story of Harry Truman's first four months in office, when this unlikely president had to take on Germany, Japan, Stalin, and the atomic bomb, with the fate of the world hanging in the balance.
