As a graduate student, Du Bois studied with two of the most important figures within what is today remembered as the German historical school of economics—Gustav Schmoller and Adolf Wagner. By taking seriously Du Bois's early ambitions in the field of economics, and rereading his early work as a social scientist in the context of early twentieth-century economic thought, the following article makes the case that Du Bois should be credited with having made several important contributions to U.S. economics. The article suggests that our failure to remember Du Bois as an economist is a joint consequence of two independent causes. The first is the racist attitudes of the U.S. academy of his time that simply would not accept a highly qualified African American as a colleague. The second is the sweeping changes that have so profoundly modified the method, form, and substance of U.S. economics over the past century.
