William Henry Fox Talbot (11 February 1800 – 17 September 1877) was a British inventor and photography pioneer who invented the calotype process, a precursor to photographic processes of the 19th and 20th centuries. Talbot was also a noted photographer who made major contributions to the development of photography as an artistic medium. His work in the 1840s on photo-mechanical reproduction led to the creation of the photoglyphic engraving process, the precursor to photogravure.
