Abstract: Papers of Bruce Barton, an author, politician, and chairman of the board of the advertising agency Batten, Barton, Durstine, and Osborn. Voluminous correspondence, which divides into general, client, and literary categories, reflects Barton's wide-ranging interests in politics, religion, advertising, business, literature, and philanthropy. The political correspondence includes letters from every President and every Republican Presidential candidate of the mid-twentieth century. Of special interest are the files for Calvin Coolidge, Thomas E. Dewey, Dwight D. Eisenhower, Herbert Hoover, and Wendell L. Willkie. There is, however, little material pertaining to Barton's own congressional career. Correspondence relating to advertising may be found chiefly in client files, including informative files on the American Tobacco Company, Du Pont, General Electric, General Mills, New York Telephone, United Fruit, and United States Steel. Literary correspondence includes exchanges with editors and publishers as well as with the readers of his many articles, editorials, and books. The papers contain a nearly-complete set of Barton's political and religious articles and addresses, either as drafts or in printed form. Also included are manuscripts for a play and several motion pictures, none of which were produced; speeches; and miscellaneous notes. Also part of the collection are the papers of Barton's father, William E. Barton, a Lincoln authority; writings by his daughter, Betsey Barton; recordings; several diaries; photographs; and miscellaneous promotional material.
