Asa Philip Randolph (April 15, 1889 – May 16, 1979) was an American labor unionist and civil rights activist. In 1925, he organized and led the Brotherhood of Sleeping Car Porters, the first successful African-American-led labor union. In the early Civil Rights Movement and the Labor Movement, Randolph was a prominent voice. His continuous agitation with the support of fellow labor rights activists against racist labor practices helped lead President Franklin D. Roosevelt to issue Executive Order 8802 in 1941, banning discrimination in the defense industries during World War II.
