Henry Fox Talbot was a British scientist, inventor, and photography pioneer, best known for his contributions to the development of photography in the 19th century. Born on February 11, 1800, Talbot was one of the first to create a method for producing photographs using a chemical process. In 1834, he developed a technique called "calotype," which involved the use of paper coated with silver iodide to create a latent image that could be developed into a negative.
