President Bumstead’s offer to lead the Atlanta Sociological Laboratory coalesced with Du Bois’s desire to develop a program of research on the color line. Upon completing research for The Philadelphia Negro, Du Bois, who quickly became a sought after scholar, was providentially offered the position of director of research at Atlanta University.

Several years prior to Du Bois’s appointment, the university institutionalized a program of research into the social, economic, and physical condition of black Americans. Du Bois was chosen to lead the Atlanta Sociological Laboratory, the term used to describe those engaged in sociological activity at Atlanta University between 18, by Atlanta University President Horace Bumstead. While each of these books, in addition to the many articles he wrote on the subject, are considered classic works in the area of race, arguably, Du Bois’s most impressive and influential research on the color line consists of the investigations he spearheaded as the director of research at Atlanta University between 18. Some of his book length treatments of the color line include his Harvard dissertation, Suppression of the African Slave Trade to the United States of America, 1638–1870, The Philadelphia Negro, and The Souls of Black Folk. Research and propaganda on the color line would be Du Bois’s life’s work.

This thunderous statement, appearing in his classic text The Souls of Black Folk, served as Du Bois’s clarion call for the nation, grappling with tense and volatile relations between blacks and whites, to engage in objective and thorough research on black Americans. In 1903, William Edward Burghardt Du Bois penned the phrase: ‘‘The problem of the twentieth century is the problem of the color line – the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea’’ (Du Bois 1994 : 9).
