The correct option is E David Walker
David Walker was born in 1796 or 1797 (some sources say 1785) in Wilmington, North Carolina. Having witnessed slavery and racism, he wrote an 1829 pamphlet, 'Appeal to the Colored Citizens of the World', that urged African Americans to fight for freedom and equality. Walker was decried for inciting violence, but also changed the abolition movement. He was 33 when he died in Boston, Massachusetts in 1830.
