The collection is the result of Major Hammer's passion for amassing material related to aeronautics and technology, and it is arranged into eleven series: articles, clippings, correspondence, drawings and blueprints, leaflets, legislation, minutes, miscellaneous, photographs, programs and publications. Housed in 23 folders, the correspondence is the most comprehensive series, reflecting the original order which grouped the letters into series by topic. Much of the correspondence concerns the planning of the Hudson-Fulton Celebration of 1909, and the involvement of Wilbur Wright and Glenn Curtiss. There is also a scrapbook of black and white photographs providing front and side views of specified airplanes. Each page has 3 photos showing different views of the same plane accompanied by a label with additional information. (See written copy for details. Also, please see information written on 8x11 notebook paper.)

The William J. Hammer Collection reflects Hammer's great interest in aeronautics --a passion he cultivated for several decades by accumulating a veritable storehouse of materials. Hammer's important contributions to the early development of aviation are also evident in this collection.
The collection of materials listed in the finding aid is arranged into two series. The first series includes correspondence, reports, handbooks, drawings, brochures, programs, leaflets, magazines, articles, newspaper clippings and miscellaneous materials. The second series is comprised of photographs of various sizes, scrapbooks, scrapbook pages and miscellaneous materials (the front pages of newspapers, certificates, posters, etc.).
Hammer's papers are arranged both chronologically and alphabetically. Correspondence, drawings, brochures, programs, leaflets, miscellaneous materials, scrapbook pages, articles and newspaper clippings are organized by the former method. Reports, handbooks, magazines and booklets are grouped alphabetically by either title of publication or author. Photographs are arranged either by subject or chronologically.
The reader should note that at some point, Hammer produced a series of large format photographs. These mounted photographs are duplicates. Due to the very fragile condition of these particular images, the photographs and are not available to researchers.
Additional photographic material regarding Hammer Collection photographs can be found in the NASM Archives Images database. An Archives staff member will assist you with research using this database.
