Portrait of African-American Social Reformer Frederick Douglass - 1874

Frederick Douglass (1818 – 1895) was an African-American social reformer, orator, writer and statesman. After escaping from slavery, he became a leader of the abolitionist movement, gaining note for his dazzling oratory and incisive antislavery writing. He stood as a living counter-example to slaveholders' arguments that slaves lacked the intellectual capacity to function as independent American citizens. Many Northerners also found it hard to believe that such a great orator had been a slave.
