Carl Lotus Becker was an American historian. He is best known for The Heavenly City of the Eighteenth-Century Philosophers (1932), four lectures on The Enlightenment delivered at Yale University. His assertion that philosophies, in the "Age of Reason," relied far more upon Christian assumptions than they cared to admit, has been influential, but has also been much attacked, Cornell has recognized his work as an educator by naming one of its five new residential colleges the Carl Becker House.
