After completing graduate work at the University of Berlin and Harvard, where he was the first African American to earn a doctorate, he became a professor of history, sociology and economics at Atlanta University. Du Bois was one of the co-founders of the National Association for the Advancement of Colored People (NAACP) in 1909.
