A daguerreotype portrait of Michael Faraday (1791-1867), taken by an unknown photographer in about 1848. Faraday is known for his pioneering experiments in electricity and magnetism. This is one of a pair of stereoscopic images intended to be viewed in a stereoscope designed by Sir Charles Wheatstone (1802-1875). In 1832, Sir Charles Wheatstone (1802-1875) first established the principles of stereoscopy. A stereograph is a pair of photographs which, when viewed through a stereoscope, give the appearance of three-dimensional depth. Stereoscopic photography became very popular in the 1850s and 1860s - particularly after it was exhibited at the Great Exhibition in 1851.
