The collected records of the Henry Ford Peace Expedition in the Swarthmore College Peace Collection are neither the official records of the Expedition nor those of the Neutral Conference for Continuous Mediation. The bulk of the materials were donated by various members of the expedition and include scattered correspondence and personal files of Louis P. Lochner, Benjamin W. Huebsch, Arthur L. Weatherly, Theodore A. Hostetler, and John E. Jones. This section of the collection includes diaries, correspondence (1915-1916), statements, speeches, passenger lists and biographies, press releases, pamphlets, the Argosy (a shipboard newsletter), menus, invitations, press credentials and visiting cards as well as clippings (1915-1925), and photographs. Also present is a file of Lochner's on Corda Fratres, an international student organization. Documents of the Neutral Conference for Continuous Mediation include minutes (1916), releases, manifestos, and bulletins. The work of the NCCM is described in the conference publications, most of which are printed in English, but include some items in French, German, Swedish, and Esperanto.
In 1999, Barbara S Kraft, the author of The Peace Ship: Henry Ford's Pacifist Adventure in the First World War, donated her extensive files of materials on the Expedition. Kraft had collected correspondence, published pamphlets, and biographical material on Expedition participants from archival collections in Europe and North America in preparation for her book. These files form Series B. of this collection.
Correspondents in the whole collection, in addition to all those named above, are Katherine Devereux Blake, Katherine Leckie, Lola Maverick Lloyd, Lewis A. Maverick, Gaston Plantiff, Frances Pogany, May Wright Sewall, and Julia Grace Wales.
