Once a year, the John D. and Catherine T. MacArthur Foundation announces its roster of MacArthur Fellows, a designation frequently referred to as the "Genius Grant." The fellowship bestows upon its recipients a $625,000 prize, along with an accolade that manages to celebrate innovative minds across fields, from science to poetry to painting, and just about everything in between. This year, the list of MacArthur Fellows ranges from a celebrated writer to an environmental advocate to an inorganic chemist, varying in age from 33 to 72 years old.
