Archives and museum collections can be filled with unique materials and objects. At the Institute archives our staff often come across many unexpected and interesting items, which caused the team to reflect on how these items came to the archives, how the items were used, who used the items, and what the items can tell us about their owners. Recently, when opening an unprocessed box our team found what we thought to be surprising yet common objects – stereoscopes.
Before the digital world and virtual reality there was the stereoscope, a three dimensional viewing device invented in the 1800s.
In the Institute archives were find some examples. These include the View-Master and the Holmes-type device.
The Holmes-type device, invented by American author Oliver Wendell Holmes, was an instrument which held a card with two images, one for each eye, that created an optical 3D illusion. The View-Master which had a disc or reel with small transparent images was introduced in 1939. It went through many changes and was ultimately outdated by the vibrant plastic versions. The Institute archive holds the Model C, which was produced from 1945 to 1955.
