Cornell history professor Margaret Washington discussed her recent major work, "Sojourner Truth's America" Oct. 12, 2009.

Washington examines Sojourner Truth's world within the broader panorama of American history, slavery and other significant reforms in the turbulent age of Abraham Lincoln, providing a view into the unlikely ascendancy of a New York black woman and former slave who was unschooled, but became a rousing preacher and political orator.
