US woman sues Harvard over 'slave ancestor' pictures

A US woman who says she is descended from slaves who were photographed in 1850 by a racist Harvard University professor on Wednesday sued the university over the "exploitation" of the images of her ancestors. Tamara Lanier filed suit in the northeastern state of Massachusetts over the photographs taken in South Carolina of a slave and his daughter, known only by their first names: Renty -- the patriarch of her family -- and Delia. The images, thought to be the earliest known photographs of American slaves, are currently in a museum at the university near Boston.
