Walker has emerged as one of the country’s preeminent voices for the arts, and social justice, and for new strategies to ameliorate inequality. He has delivered the annual Nancy Hanks Lecture sponsored by Americans for the Arts and was the subject of a glossy profile in the New York Times titled “The Man With the $13 Billion Checkbook.” And in September, the National Gallery of Art announced that Walker would be joining its board, one of the smallest and most exclusive governing bodies in the art world, with only nine members, four of them ex officio positions, including the chief justice of the United States and the secretaries of the Treasury and State departments. – Washington Post
