Scope and Contents
This collection consists of material relating to Manly's aeronautical career, specifically his work with Samuel Langley's Aerodrome. The material consists of programs, publications, newspaper clippings, work notebooks, waste books, (mostly letterpress) and correspondence between Manly and the aviation and Smithsonian communities, circa 1885-1925. Correspondents include Samuel Langley, Charles Walcott and Richard Rathbun of the Smithsonian; Cyrus Adler, Glenn Curtiss, Benjamin D. Foulois, Carl Myers, Frank Lahm, and Augustus Post. Of particular interest is the correspondence between Manly and Smithsonian Secretary Charles Walcott on Manly's work on the preparation of the Langley Memoir on Mechanical Flight for publication between 1908 to 1911; and his correspondence with Glenn Curtiss concerning the test flights of the rebuilt Great Aerodrome on Lake Keuka, Hammondsport, New York, in 1914, and the resulting controversy between the Smithsonian and Orville Wright.
