Plot synopsis: He went off to war an unknown soldier and returned a beloved national hero. Often dismissed as a "do-nothing" president and a good-natured bumbler, Dwight D. Eisenhower -- the last American president to be born in the 19th century -- was actually a skillful politician, a tough Cold War warrior, and one of America's most misunderstood and unappreciated presidents. Two-part documentary from American Experience.
