Stereographic Collection

Invented by Charles Wheatstone in 1838, the stereoscope device added an entirely new dimension to the burgeoning field of photography. Utilizing a stereo card (two copies of essentially the same image with one partially offset on a single card), the viewer placed the card in the scope to see the image in three dimensions. Around the year 1860, poet Oliver Wendell Holmes created a handheld stereoscope consisting of two prismatic lenses and a wooden stand to hold the stereo card. The Holmes stereoscope was the most commonly produced version in the 19th century and remained in production for more than a century.
