As a chemist, Michael Faraday (1791-1867) was also interested in the new art of photography and
corresponded with scientists on the subject. He was photographed an extraordinary number of times. The photographs of Faraday held in the Institute of Engineering and Technology Archives
include a very early example of a calotype (an early photographic process where the image is produced on paper treated with silver iodide and allowed to develop in sunlight) and a telephotograph.
Recently, a series of his Royal Institute evening lecture notes, compiled by Maria Herries, including one on The Daguerreotype
in 1848, was sold at Bonhams for £5,400. Full description of the lot can be found here
