Raynard S. Kington, the new president at Grinnell College, said he was attracted to the institution by its commitment to social justice. The college has now announced a new award -- in which up to $300,000 will be awarded annually to honor people under the age of 40 who have demonstrated leadership in promoting positive social change. Up to three awards -- each splitting $100,000 between an individual and an organization committed to the individual's ideals of social justice -- will be made each year.
