Correspondence, manuscripts, articles, clippings, scrapbooks, printed matter and memorabilia relating chiefly to Arthur Knapp’s yachting activities. The original subject files have been retained, but each file has been reorganized chronologically insofar as possible. Owing to the brittle condition of the newspaper clippings in the collection, most have been photocopied and the originals discarded. Loose photographs found in the files were transferred to the Museum’s general collection.

Some material was added to Arthur Knapp’s own collection by his daughter, Corliss Knapp Engle, after his death.
