W.E.B. DuBois (pronounced /duːˈbɔɪz/ doo-boyz; February 23, 1868 – August 27, 1963) was an American sociologist, historian, civil rights activist, Pan-Africanist, author, and editor. Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. 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.
