W.E.B. DuBois, the black American sociologist, scholar, author, pan-Africanist, communist, and one of the founders of the NAACP, died in Accra, the capital of Ghana, on August 27, 1963, where he had expatriated. He had been charged and tried in the U.S. for being a "foreign principle" in 1951 because he chaired the The Peace Information Center. It was dedicated to banning nuclear weapons but Secretary of State Dean Acheson designated it a Communist front. He was 95.
"Children learn more from what you are than what you teach. —WEB Dubois, 1897
Meanwhile, on August 28, 1963, only a day after DuBois' passing, Martin Luther King delivered the speech for which he is best remembered: "I have a dream." You can read the speech here or you can watch a vid here.
