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.

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...
