Keystone View Company

The Keystone View Company was founded in Meadville, Penn., by Pennsylvania native B. L. Singley (1864-1938), who had been a salesman for the stereographic producer and distributor Underwood & Underwood. The first prints sold under the Keystone name were Singley’s own photographs of the 1892 French Creek flood. Incorporated in 1905, Keystone opened its Educational Department, creating products designed for classroom use, with an emphasis on social studies, geography, and the sciences. As the company grew, with branch offices in several major cities and staff photographers all over the world, it acquired the stereographic inventories of several of its competitors, including Underwood & Underwood, becoming the largest company of its kind in the world. In 1932, Keystone launched its Stereophthalmic Department, which included stereoscopic vision tests and products for correcting vision problems. Singley retired as Keystone’s president in 1936 or 1937, and Keystone was bought by Mast Development Company in 1963.

This 1923 boxed set, World War Through the Stereoscope, part of the “Stereographic Library” and housed in a box imitating the look of a two-volume set of books, contains 100 images of World War I and just after, taken ca. 1917-1921. The stereographic prints are pasted onto Keystone’s distinctive grey curved mounts, with extensive descriptive information on the reverse of each mount. Prints are numbered with identifiers—those beginning with “V” were originally Underwood photographs—as well as numbers indicating the order in which they are to be viewed. The stereographs are accompanied by a viewer, also manufactured by Keystone.
