 After Otto Neurath’s death in 1945, Marie Neurath and her collaborators continued to apply Isotype to tasks of representing many kinds of complex information, especially in popular science books for young readers.A real test of the international ambitions of Isotype, as Marie Neurath saw it, was the project to design information for civic education, election procedure and economic development in the Western Region of Nigeria in the 1950s.In 1971 the Isotype Institute gave its working material to the University of Reading, where it is housed in the Department of Typography & Graphic Communication as the Otto and Marie Neurath Isotype Collection.
