Moorfield Storey (1845–1929), a prominent constitutional lawyer and past president of the American Bar Association, became the NAACP’s first president (1910–1929). He was descended from the New England Puritans and Harvard trained. A steadfast champion of the oppressed, he also served as secretary to abolitionist Senator Charles Sumner; led the Anti-Imperialist League, which opposed U.S. ownership of the Philippines; and defended the rights of Native Americans and immigrants. Storey prosecuted the NAACP’s early Supreme Court victories. He was later aided by Louis Marshall (1856-1929), another renowned constitutional lawyer and Jewish communal leader.
