Claudet, Antoine Francois obtained the first British license to make dagurreotypes in England. That was in 1840. In June of 1841 he opened a studio on the roof of the Royal Adelaide Gallery, but his studio wasn't the first. Richard Beard had opened one in March. Claudet was an important innovator. He made many improvement to the process and became a successful photographer. He invented the use of a red safety light in the dark room so he could see what he was doing without exposing the plate. In 1851 he began making stereo daguerreotypes, starting a craze. Estimated basic value: $1700
