John D. and Catherine T. MacArthur Foundation

The John D. and Catherine T. MacArthur Foundation supports creative people, effective institutions, and influential networks building a more just, verdant, and peaceful world. MacArthur is placing a few big bets that truly significant progress is possible on some of the world’s most pressing social challenges, including advancing global climate solutions, decreasing nuclear risk, promoting local justice reform in the U.S., and reducing corruption in Africa’s most populous country, Nigeria. In addition to the MacArthur Fellows Program and the global 100&Change competition, the Foundation continues its historic commitments to the role of journalism in a responsive democracy as well as the vitality of our headquarters city, Chicago.
