The polar collection that Stef assembled in his later years was initiated by a gift to him of three hundred books by the American Geographical Society. By now the collection, the property of Dartmouth College, numbers some twenty-five thousand bound volumes and forty-five thousand manuscripts, pamphlets, and the like. His widow, the former Evelyn Schwartz Baird, is still its able librarian, and until the end Stef could be seen quietly at work in a corner of the stacks that hold this vast assemblage of polar information.
