Brewster brand stereoscopic viewer made of thuya burl wood, manufactured from 1851 in England.
 Stereoscopic photography is as old as "flat" photography (the kind of photography we know today). The invention of stereoscopic images even predates photography itself, since in 1838, Wheatstone, a member of the Royal Society of London, invented a mirror-based device that reproduced depth (as a reminder, the official date of the invention of photography is 1839). Furthermore, the principle of obtaining a stereoscopic image had already been established in antiquity by Euclid and further developed by Leonardo da Vinci in 1484.
