Holmes Stereoscopes
A stereograph is composed of two pictures mounted next to each other, viewed with a set of lenses known as a stereoscope. Taken around 7cm apart, roughly corresponding to the spacing of the eyes, the left picture represents what the left eye would see, and likewise for the right, so when observing the pictures through a stereoscopic viewer, the pair of photographs converge into a single three-dimensional image.
Oliver Wendell Holmes Sr. invented the version of the stereoscope that you can use today in Lichtenwalter Schoolhouse in 1860. This optical marvel took the world by storm in the mid 19th century, becoming the first ever mass-produced photographic images sold, and a precursor to the motion picture phenomena. They were so popular that it is said that every Victorian home—regardless of class—had a stereoscope and a collection of views sold in a range of prices.
