(1797–1867), French photographer and scientist, active in England. He became an influential London portrait photographer at his Adelaide Gallery studio, licensed by the inventors to practise both the daguerreotype and the calotype. Claudet's earliest significant technical contribution, in 1841, was in greatly increasing the sensitivity of the daguerreotype plate, thus reducing exposure times and making the process much more suitable for portraiture. In 1851 he moved to Regent Street, where he also began using the wet-plate process. Claudet published prolifically on photography, vision, and the photographic representation of sculpture. He was also one of the foremost early practitioners of stereoscopic photography, inventing a folding stereoscope and other devices. Many of Claudet's impressive photographs survive, but his collection of historical photographic incunabula was destroyed by fire after his death.
