Illustration of William Henry Fox Talbot (1800-1877), British photography pioneer. Talbot is best known for his development of the calotype, an early photographic process that was an improvement over the daguerreotype of the French inventor Louis Daguerre. Talbot's calotypes involved the use of a photographic negative, from which multiple prints could be made. Had his method been announced a few weeks earlier, he, and not Daguerre, would probably be remembered as the founder of photography. Image published in 1859.
