Scholar Reappraises President Lincoln

In a new documentary that begins airing Wednesday on PBS, scholar Henry Louis Gates Jr. tries to uncover the real man. In Looking for Lincoln, the director of the W.E.B. Du Bois Institute for African and African American Research at Harvard University discovers the 16th president may have been known as the great emancipator, but he also told racist jokes and hoped to resolve America's racial dilemma by sending blacks back to Africa.
