Frederick Douglass. Born into slavery around 1818, Douglass became a key leader of the abolitionist movement. On July 5, 1852, in Rochester, New York, Douglass gave one of his most famous speeches, “What to the Slave Is the Fourth of July?” He was addressing the Rochester Ladies’ Anti-Slavery Society. James Earl Jones reads the historic address during a performance of Voices of a People’s History of the United States, which was co-edited by Howard Zinn. The late great historian introduces the address.
