Written in 1955 by the then junior senator from the state of Massachusetts, John F. Kennedy's Profiles in Courage served as a clarion call to every American. The inspiring true accounts of eight unsung heroic acts by American patriots at different junctures in our nation's history, Kennedy's book became required reading, an instant classic, and was awarded the Pulitzer Prize. Now, a half-century later, it remains a moving, powerful, and relevant testament to the indomitable national spirit and an unparalleled celebration of that most noble of human virtues. This special "P.S." edition of Profiles in Courage commemorates the fiftieth anniversary of the book's publication. Included in this new edition, along with vintage photographs and an extensive author biography, are Kennedy's correspondence about the writing project, contemporary reviews of the book, a letter from Ernest Hemingway, and two rousing speeches from recipients of the Profile in Courage Award.

<blockquote>"This is a book about that most admirable of human virtues-- courage. 'Grace under pressure,' Ernest Hemingway defined it. And these are the stories of the pressures experienced by eight United States Senators and the grace with which they endured them."
-- John F. Kennedy</p></blockquote>
During 1954-1955, John F. Kennedy, then a U.S. Senator, chose eight of his historical colleagues to profile for their acts of astounding integrity in the face of overwhelming opposition. These heroes include John Quincy Adams, Daniel Webster, Thomas Hart Benton, and Robert A. Taft.</p>
Awarded the Pulitzer Prize in 1957, Profiles in Courage -- now reissued in this handsome hardcover edition, featuring a new introduction by Caroline Kennedy, as well as Robert Kennedy's foreword written for the memorial edition of the volume in 1964 -- resounds with timeless lessons on the most cherished of virtues and is a powerful reminder of the strength of the human spirit. It is as Robert Kennedy states in the foreword, "not just stories of the past but a hook of hope and confidence for the future. What happens to the country, to the world, depends on what we do with what others have left us."</p>
