Educated at Fisk, Harvard, and the University of Berlin, Du Bois was first and foremost an academic. He was also a writer, editor, sociologist, historian, poet, and civil rights activist. He believed "scientifc study" was the key to solving most of the world's ills (particularly the problem of the color line in the United States and the problem of third world oppression globally) and dedicated his life to this kind of study. For Du Bois, being smart in the world mattered. More than that, being smart obligated you to making a difference. It is his example I think of when I need reminding that I'm not wasting my life away as an academic.
