His singular greatness lay in his quest for truth about his own people.
Du Bois was a tireless explorer and a gifted discoverer of social truths.
In 1897, he directed the Atlanta Conferences which convened annually to generate concise scientific research on the living conditions of African Americans.
From those conferences he collected, collated, and analyzed socioeconomic data about every conceivable facet of being a black person in America.
Ambitious at the time and still is he published about sixteen volumes on his findings.
In 1903, he published his first of remembered works The Philadelphia Negro and later the Souls of Black Folks.
Du Bois plunged himself into anthropological, sociological, historical, economic, and philosophical studies of blacks in America hoping to elude a "cure" for the race problem in America.
He was editor for the Crisis, the official magazine for the NAACP (National Association for the Advancment of Colored People) which he helped to find in 1910.
He used his knowledge and position to write many influential articles on blacks in America. As a representative of the NAACP he went to the Peace Conference after the Armstice was signed at the end of World War I.
He organized a Pan African Conference (he wasn't the founder) to discuss the situations of AFricans everywhere, realizing for blacks to be free they must be free everywhere.
