The Hales Bar Dam was built on the Tennessee River to improve river navigation and produce hydroelectric power. Construction work on the dam, which took place from 1905 to 1913, faced engineering challenges and leaks due to the broken and creviced limestone beneath the dam. The collection spans 1905-1968 and includes papers, reports, drawings and photographs related to the construction of the dam, as well as documents related to its maintenance in the decades following its completion.
Sixty-six pages from a photograph album compiled by an anonymous photographer, documenting the Philadelphia-Camden or Delaware River Bridge, now called the Benjamin Franklin Bridge.
The records document the work of consulting engineers and bridge builders, Ralph Modjeski (1861-1940) and Frank Masters (1883-1974) of Harrisburg, Pennsylvania.
The collection documents the career of George S. Morison, a prominent civil engineer, specializing in railroad bridge design. The materials consist primarily of drawings and maps (linen tracings, blueprints, sketches); final bridge reports; photographs; glass plate negatives; daily diaries; correspondence; and published material documenting George S. Morison's participation on the Isthmian Canal Commission, 1898-1903.
These records consist of project files for the renovation or improvement of facilities for various Smithsonian Institution buildings, particularly the construction of the Hirshhorn Museum building. Materials include blueprints and architectural drawings, specifications, correspondence with contractors, payroll sheets, progress and inspection ...
Photographs of West Africa, mostly from Lagos and coastal Nigeria, 1877-1895. There are high quality pictures of trading houses and residences in Lagos, often with the name of the owners given in the caption. One of the buildings depicted is the cathedral. Several exceptional images portray chiefs, such as the King of Opobo, and the wives of the King of Opobo, the Balogun of Epe, the Alake of Abeokuta, and the chief of New Calabar. Of greatest interest is a photograph entitled "Benin Gods" which shows figures from the Kingdom of Brass, taken in circa 1877/1878. There are also views of Cape Coast, Elmina, Accra, Wydah, Fernando Poo, Porto Novo, Grand Popo, and one from Liberia. The themes range from architecture to dances and weddings. Of particular interest are two depictions of fancy dress.
This record unit contains some information on post-World War II exhibition planning at the Smithsonian. However, in the main, they document the involvement of the Office of the Director in exhibition planning at the Museum of History and Technology (MHT) from its creation in 1957 through 1965. Directors represented in this collection include ...
The collection consists of correspondence, invoices, drawings, photographs, and negatives and other printed literature documenting the Baltimore and Ohio Railroad from its inception in 1827 to its merger with the Chesapeake and Ohio Railroad in the 1960s.
The papers document the life and work of William R. Hutton, a civil engineer during the late 1800s to the early 1900s. Materials include diaries, notebooks, correspondence, letterpress copy book, printed materials, publications, specifications, photographs, drawings, and maps that document the construction of several architectural and engineering projects during this period. Most notable are the records containing information related to the construction of the Chesapeake and Ohio Canal, Hudson River Tunnel, the Washington Aqueduct, the Kanawha River Canal, and the Washington/Harlem River Bridge. There are also several records about railroads in the state of Maryland, the District of Columbia and elsewhere, including the Western Maryland Railroad, Baltimore and Ohio Railroad, Colorado Midlands Railway, Baltimore and Drum Point Railroad, the Northern Adirondack Railroad, and the Pittsfield and Williamstown Railroad. The records can be used to track the progression of these projects, and engineering innovation during the late 1800s to the early 1900s.
