From 1897 to 1910, Du Bois taught economics and history at Atlanta Univ. In 1910 he became editor of the influential NAACP magazine, Crisis, a position he held until 1934. That year he resigned over the question of voluntary segregation, which he had come to favor over integration, and returned to Atlanta Univ. (1934-44). His concern for the liberation of blacks throughout the world led him to organize the first (Paris, 1919) of several Pan-African Congresses. In 1945, at the Fifth Congress in Manchester, England, he met with the African leaders Kwame Nkrumah and Jomo Kenyatta. In 1961 he became a member of the American Communist party, and shortly thereafter he renounced his American citizenship. In the last two years of his life Du Bois lived in Ghana. His books include The Souls of Black Folks (1903), The Negro (1915), Black Reconstruction in America (1935), Color and Democracy (1945), The World and Africa (1947), and In Battle for Peace: The Story of My 83rd Birthday (1952).
