For years there existed a rumor that Thomas Jefferson had a long-standing relationship and several children by Sally Hemings, a woman who was his slave. Now, DNA tests all but prove the rumor true. An early hero of the anti-slavery movement, Jefferson wrote brilliantly of the corrupting influence of slavery on blacks and whites alike. Yet it is now apparent that he lived a dual life, sharing his house with his white daughter and grandchildren while his unacknowledged mistress and his children by her worked in the same house as slaves. In a personal essay, FRONTLINE correspondent Shelby Steele examines Jefferson's life and follows the descendants of Jefferson and Hemings as they undergo DNA testing, search out their family history, and try to sort out their place along America's blurred color line.
