Correspondence, writings, memorabilia, scrapbooks and printed matter chiefly concentrated in the years 1910-1923. The correspondence includes photocopies of thirteen letters from Woodrow Wilson to Hale (1911-1915) discussing various aspects of United States foreign policy. Between 1913 and 1914, Hale travelled in Central America as Woodrow Wilson's special emissary to Mexico and then to Nicaragua. His letters to his wife during this period describe the political upheavals in those countries and his opposition to United States recognition of the Huerta government in Mexico. Also of note are three letters from Sigmund Freud in which Freud discusses the proper use of psychoanalysis in connection with Hale's just published study of Woodrow Wilson. Other important correspondents include William Jennings Bryan, John Burroughs, Thomas Hardy, Oliver Wendell Holmes, William Dean Howells, H. L. Mencken, Theodore Roosevelt and George Bernard Shaw. There is only a small sampling of his writing and one sermon. The largest part of the collection is made up of scrapbooks and printed matter (1914-1923), reflecting Hale's position during World War I as a secret agent of the Germans. Included are pro-German periodicals and pamphlets published before the United States entry into the war and post war pamphlets on the question of German war guilt and the Versailles Treaty.
