W. E. B. Du Bois
Atlanta University

In July 1897, Du Bois left Philadelphia and took a professorship in history and economics at the historically black Atlanta University in Georgia. His first major academic work was his book The Philadelphia Negro (1899), a detailed and comprehensive sociological study of the African-American people of Philadelphia, based on his fieldwork in 1896–1897. This breakthrough in scholarship was the first scientific study of African Americans and a major contribution to early scientific sociology in the U.S.

Du Bois coined the phrase "the submerged tenth" to describe the black underclass in the study. Later in 1903, he popularized the term, the " Talented tenth ", applied to society's elite class. His terminology reflected his opinion that the elite of a nation, both black and white, were critical to achievements in culture and progress. During this period he wrote dismissively of the underclass, describing them as "lazy" or "unreliable", but – in contrast to other scholars – he attributed many of their societal problems to the ravages of slavery.

Du Bois's output at Atlanta University was prodigious, in spite of a limited budget: he produced numerous social science papers and annually hosted the Atlanta Conference of Negro Problems. He also received grants from the U.S. government to prepare reports about African-American workforce and culture. His students considered him to be a teacher that was brilliant, but aloof and strict.
