Essie Mae Washington-Williams is the daughter of the late Sen. Strom Thurmond. While her mother, who was black, served as the maid for the Thurmonds, she had an affair with the future senator, at the age of 15. Thurmond was a long-time senator from South Carolina and an opponent of integration. Washington-Williams did not reveal her true identity as Thurmond's daughter until after his death at 100 a little more than a year ago. Now 78, she has written a new memoir, Dear Senator: A Memoir by the Daughter of Strom Thurmond.
