Who invented stereoscopic photography? 

In 1838, a year before the invention of photography, British physicist, Sir Charles Wheatstone, was conducting experiments with stereoscopic vision: the slightly different images created by two eyes when looking at an object. That same year he invented a rudimentary stereoscope.

In 1842, the first attempt to create a stereoscopic photograph was made by French-born British daguerreotypist Antoine Francois Claudet. But it would take almost a decade for Scottish physicist, Sir David Brewster, to overcome the limitations of the previews models.  In 1849, the stereograph became a commercial reality by utilizing the reproductability of collodion wet plate process instead of glass plates and daguerreotypes.
