Journalist. Knickerbocker was a student in journalism at Columbia University, 1919-1920, and a foreign correspondent for the New York EVENING POST and the Philadelphia PUBLIC LEDGER, and later for the International News Service.

Correspondence, clippings, notebooks, and photographs. The principal files are not complete. The correspondence covers the years 1920 to 1941, and the scrapbooks of clippings begin in 1927 and end in 1945. Nevertheless, many of Knickerbocker's reports, cables, and interviews, some unpublished, are present and provide information concerning news events, primarily in Europe, and the operations of his office. Correspondence with fellow members of the press is extensive and interesting. There are a few original manuscripts in the collection, but none pertain to Knickerbocker's seven books. Also, photographs relating to Knickerbocker's works on Russian trade and the Five Year Plan, and of Knickerbocker himself. The correspondence includes letters from Winston Churchill, Randolph Churchill, Evelyn Waugh, Leon Trotsky, Sir Josiah Stamp, Ernestine Evans, Walter Duranty, and John W. Wheeler-Bennett.
