Through a rich interpretation of the remarkable photographs W. E. B. Du Bois compiled for the American Negro Exhibit at the 1900 Paris Exposition, Shawn Michelle Smith reveals the visual dimension of the color line that Du Bois famously called the problem of the twentieth century. Du Boiss prize-winning exhibit consisted of three albums together containing 363 black-and-white photographs, mostly of middle-class African Americans from Atlanta and other parts of Georgia. Smith provides an extensive analysis of the images, the antiracist message Du Bois conveyed by collecting and displaying them, and their connection to his critical thought. She contends that Du Bois was an early visual theorist of race and racism and demonstrates how such an understanding makes the important concepts he developedincluding double consciousness, the color line, the Veil, and second sightavailable to visual culture and African American studies scholars in powerful new ways.
