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. Talbot is also remembered as the holder of a patent which, some say, affected the early development of commercial photography in Britain. Additionally, he made some important early photographs of Oxford, Paris, Reading, and York.
