Keystone View Company

The Keystone View Company was a major distributor of stereographic images, and was located in Meadville, Pennsylvania.

The Hall of Fame Annual[3] states that while Singley was a college student James M. Davis showed him a stereograph of two silver gray foxes in the woods.

Gazing at the three-dimensional image caused Singley to understand the educational potential of stereoscopic photography, and enkindled in him a desire to teach others through the use of stereoviews.

Singley photographed the damage, developed multiple prints of 30 negatives and pasted them on cardboard mounts bearing the name of Keystone View Company.

All of the manufacturing was done in Meadville, but branch offices were in New York, St. Louis, San Francisco, Portland, Oregon, Chicago, Toronto, Canada, and London, England.

Over the years hundreds of educational sets were marketed to teach geography, social studies, science, history and reading.

[8] Keystone View Company produced stereographic sets up through the mid-twentieth century, and had a stereoscopic photographer on staff until at least 1955.

For those diagnosed with certain vision problems special Keystone stereoscopes and stereoviews were used in the home for daily eye-training exercises.

[12] As a subsidiary of Mast Development Company, Keystone produced telebinoculars, eye training products and overhead projectors.

In 1972 Gifford Mast closed down the Meadville manufacturing site, although the name of Keystone View Company continues to be used on eye training equipment.

[13] In 1978, the company's records and inventory of negatives, weighing more than 30 tons, were donated to the UCR/California Museum of Photography at the University of California Riverside, where they are now known as the Keystone-Mast collection.

In 2002, the Johnson-Shaw Stereoscopic Museum opened in Keystone View's hometown of Meadville to celebrate the company.

Keystone Press Agency had branches or independent sole proprietorships in New York, Montreal (Bob Moynier, 1960), Paris, Brazil (Agnes Garai),[20] and London (Bertram Garai).. Keystone Press Agency London was founded in 1918[21] by Bertram (Bert?)
