About This Collection

This collection consists of glass lantern slides and syllabuses for the course “The Materials of Engineering Construction.” It was the first in a series of four courses in Civil Engineering, developed by Samuel Tobias Wagner and taught at the Wagner Free Institute of Science between1893 and 1950. The course discussed the properties, mining, and manufacturing of the various materials used in civil engineering, including stone, brick, cement, concrete, wood, iron, and steel. Of note in the collection are photographs of quarries and furnaces in Swedeland, PA and photos of the Phoenix Iron Co., Phoenixville, PA.
