Overview and metadata sections

The original Fritz Engineering Laboratory was funded, designed and built by John Fritz beginning in 1909 and dedicated in 1910. The original laboratory was designed as a one-quarter scale building of a building also designed by John Fritz, known as the Number 2 Machine Shop, for the Bethlehem Iron Works (predecessor to the Bethlehem Steel Company/Corporation). Mr. Fritz also provided the largest test machine, an 800,000 lb Riehle Universal Testing Machine, in the world at the time for his laboratory. This machine tested some of the structural plates manufactured by McClintic-Marshall (1888 civil engineering alumni) for the Panama Canal as well as the cable anchorages designed by Bethlehem Steel Company for the first Tacoma Narrows Bridge (it was the bridge design not the cable anchorages that caused this bridge to fail so spectacularly). By the mid 1930s a need to expand was indicated and Professor Hale Sutherland, head of the civil engineering department, made an attempt to build an addition but the economic situation at the time thwarted the attempt. A graduate degree program in civil engineering had been introduced in 1927/28 and research work expanded greatly. By 1951 another attempt was made to expand by Professor William J. Eney. With the help of the Bethlehem Steel Corporation, Professor Eney succeeded in having built a seven story steel frame addition. The building’s cornerstone was laid in June, 1954 and by October, 1955 the addition, known as “the new” Fritz Laboratory, was dedicated. Professor Eney, following in John Fritz’s footsteps, also had installed in the addition the largest test machine in the world, a 5,000,000 lb. Baldwin Universal Testing Machine which got its claim as largest because of an addition made to its height to accommodate very long structural members. This laboratory addition and testing machine made Lehigh’s civil engineering department and the Fritz Engineering Laboratory world famous. Many visitors from around the world came to participate in unique, innovative research testing noteworthy enough to appear in newspapers and articles in many professional journals. During these years, Fritz Lab particularly tested steel and concrete specimens for both commercial and Lehigh-based research.

This collection is comprised of over 6,500 photographs and negatives depicting testing and related activities in the Fritz Engineering Laboratory on the campus of Lehigh University during the mid-to-late 1950s.

The collection is currently housed in nine boxes. Each box contains approximately thirty folders and each folder contains approximately 10-20 sleeves. Each sleeve contains at least one individual photograph, negative, or film strip. Many sleeves contain multiple items in various formats and sizes, while some contain additional inner sleeves and items. The sleeves are marked with an identifying number, assigned by Fritz Laboratory. Usually, this includes a laboratory project number. Project numbers included in the collection are: 146, 157, 165, 166, 170, 171, 173, 174, 175, 176, 180, 181, 184, 185, 188, 189, 191, 193, 194, 195, 196, 200, 203, 204, 205, 205A, 205B, 205C, 205D, 205E, 206, 208, 211, 223, 224, 229, 233, 236, 237, 240, 241, 242, 243, 244, 245, 246, 248, 249, 256, 265, 268, 269, 271, 275, 277, 286, 304, and 354.All materials are in black and white.

Images organized by original containing boxes and by project numbers assigned by Fritz Laboratory. Items then organized by item number, also assigned by the laboratory, or are organized by this number when project numbers are not present. In effect, the project is largely organized chronologically in the Laboratory’s system.

In 2013, Lehigh University has been awarded a $93,700 grant by the Council on Library and Information Resources (CLIR) Cataloging Hidden Special Collections and Archives Program, funded by the Mellon Foundation to process and create finding aids for six civil engineering archival collections, including the papers of John Fisher; Blair Birdsall; Willis Slater; Council on Tall Buildings and Urban Habitat; series of photographic prints and negatives of civil engineering testing, and collection of bridge postcards. The Project started in March 2014 and completed in March 2016.

The processing of this collection was made possible through generous funding from The Andrew W. Mellon Foundation, administered through the Council on Library and Information Resources' "Cataloging Hidden Special Collections and Archives" Project. Created in 2008, the Cataloging Hidden Special Collections and Archives awards program supports the identification and cataloging of special collections and archives of high scholarly value that are difficult or impossible to locate. It is administered by the Council on Library and Information Resources in Washington, D.C. Award recipients create descriptive information for their hidden collections that will eventually be linked to and interoperable with all other projects funded by this grant program.
