Alexander Graham Bell, Chichester Bell, and Tainter established the Volta Laboratory Association in 1881. This collection presents a comprehensive picture of the early development of the phonograph and Tainter's substantial contributions to the project.

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.)
