Invention of the
Sir Charles Wheatstone invents Stereoscope (aka Wheatstone’s Stereoscope).
This was also introduced before photography was available, so illustrations were used.
First Stereographic Photograph
Replacing Wheatstone’s stereographic drawings a couple of years later were stereographic photographs.
Stereographic photos use two photographs, one for each eye, placed about 2.5 inches apart, side by side.
When looking through a tereoscope, these two flat images become 3D.
Lenticular Stereoscope Invented
Aka Brewster’s Stereoscope. Sir David Brewster (Wheatstone’s Rival), credits the invention from 1823 to Mr Elliott a “Teacher of Mathematics”. Brewster makes it clear that his contribution to the invention was to suggest adding lenses to unite the different images. Hence, the Lenticular Stereoscope (lens based) becomes Brewster’s invention.
Brewster’s version is smaller and hand held. In 1861 Oliver Wendell Holmes innovated this invention to a more ergonomic and economical handheld device. He deliberately did not patent his design. It is also known as the “American”, “Mexican” or Holmes Stereoscope.
The Queen sends Brewster’s Stereoscope sales Rocketing
Queen Victoria digs the Brewster Stereoscopes the best at the Great Exhibition (aka the Great Industrial Exhibition), aka the first Manufactured Goods World Expo 1851! So do another 250k peeps! Quarter of a million sales in 3 months!
This magnificent show of Industrialism was displayed at the Crystal Palace London, specially built for the exhibition
