Abstract
The collection of photographs illustrate various types of civil engineering works including the Whipple through truss railroad bridge, Pennsylvania through truss bridge, suspension bridges, cantilever bridges, reinforced concrete arch bridges and buttress dams. Among the bridge photographs are included the Brooklyn Bridge, the Firth of Forth Bridge, the Tay Bridge and Niagara Falls “Honeymoon” Bridge collapses, the Pecos River railroad trestle bridge and the “Luten Design” reinforced...

Abstract
This journal appears to be a unique record
of daily on site observations and construction processes of the building of a second Harlem
River bridge at the site of Third Avenue, County of New York (Manhattan). It contains copied
documents such as the New York State Legislature’s document Chapter 774 dated April 17, 1857
authorizing the building of a new bridge at the site, as well as the design requirements for
the new bridge, removal of the previous bridge and the official appointment and...
In 1955 Fritz Engineering Laboratory, originally built by John Fritz in 1909-1910, dedicated a new seven-story addition known as the new Fritz Laboratory. From that time on there was a systematic filing of research reports. Before this date the research reports in Fritz Laboratory were not designated systematically. This collection of manuscripts was produced or collected by faculty prior to 1955.
Henry S. Jacoby Papers contains diplomas and certificates he received, drawings and illustrations for some of his books, scrapbooks about Lehigh (1872-1877), typescripts of some of his publications, and correspondence to and from the American Railway Engineering Association. The correspondence is of special to any engineer interested in the work involved in formulating a textbook or the forensics of old bridges.
Abstract
This collection contains an incomplete series of photographs taken by Andrew J. Russell under the direction of Herman Haupt. These photographs capture different methods for the construction and deconstruction of bridges and other engineering projects implemented during the Civil War to aid military transportation. These photographs are described in detail by Haupt in the accompanying text volume. A series of images, many of which appear to be illustrations of scenes depicted in the...
Informative journal of travels in the region of Puno and Cuzco containing information about the Andean culture, indigenous populations, places, topography, Andean Indian ruins and building features. During the Davis exploration of southeastern Peru he was joined by American archaeologist and U.S. Commissioner to Peru, Ephraim George Squier and together they measured and observed with great care the Inca ruins in the Cuzco region.
Abstract
The album contains a collection of photographs of six Pennsylvania bridges and several railroad works possibly inspected by G. W. Philips in a period from 1900 to 1930. Perhaps the most well-known Pennsylvania bridge is the multi concrete arch Hyner Bridge over the Susquehanna River near Renovo, Pennsylvania. The Hell Gate Bridge over the East River in New York City is an anomaly among the construction photographs in the album as the only New York bridge. The album is an interesting...

Abstract
This manuscript contains three bridge
design class exercises indicating the instructional process to train engineering
students. Specific step-by-step instruction in designing for various railroad bridge
spans, building material specifications, structural loads and stresses to be
considered as presented in the professor’s lecture. The complete process of
calculating the design with comparisons of different conditions, as well as material
available, costs incurred of every aspect of the...
Abstract
Documents and photographs related to Lehigh University Civil Engineering faculty William J. Eney's early teaching years (1930s) at civil engineering summer camps (Canadensis, Pa.) including his lecture documents on bridge engineering, his own invention of testing equipment, correspondence between Smithsonian Institution and Lehigh University about Eney Deformeter, photographs and documents about construction of Fritz Engineering Laboratory addition and Baldwin Universal Testing Machine...
