W. E. B. Du Bois was a prolific author, renowned sociologist, fierce civil rights advocate, co-founder of the NAACP, and a historian of black lives. He was also a pioneer of data visualization. Working with ink, gouache, graphite, and photographic prints, Du Bois and his student and alumni collaborators at Atlanta University generated crisp, dynamic, and modern graphics as a form of infographic activism. 63 brightly colored broad sheets were exhibited in Paris and made 20 years before the founding of the Bauhaus.These visualizations offer a prototype of design practices now vital in our contemporary world—of design for social innovation, data visualization in service to social justice, and the decolonization of pedagogy.
