William Henry Fox Talbot (11 February 1800 - 17 September 1877), was the inventor of the negative / positive photographic process, the precursor to most photographic processes of the 19th and 20th centuries. He was also a noted photographer who made major contributions to the development of photography as an artistic medium. His work in the 1850s 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, and York.

Talbot was the only child of William Davenport Talbot, of Lacock Abbey, Wiltshire, and of Lady Elisabeth Fox Strangways, daughter of the 2nd Earl of Ilchester. Talbot was educated at Rottingdean, Harrow and at Trinity College, Cambridge, where he was awarded the Porson prize in Classics in 1820, and graduated as twelfth wrangler in 1821. From 1822 to 1872, he frequently communicated papers to the Royal Society, many of them on mathematical subjects. At an early period, he had begun his optical researches, which were to have such important results in connection with photography. To the Edinburgh Journal of Science in 1826 he contributed a paper on "Some Experiments on Coloured Flame"; to the Quarterly Journal of Science in 1827 a paper on "Monochromatic Light"; and to the Philosophical Magazine a number of papers on chemical subjects, including one on "Chemical Changes of Colour."

Talbot engaged in photographic experiments beginning in early 1834, well before 1839, when Louis Daguerre exhibited his pictures taken by the sun. After Daguerre's discovery was announced (without details), Talbot showed his four-year old pictures at the Royal Institution on 25 January 1839. Within a fortnight, he freely communicated the technical details of his photogenic drawing process to the Royal Society. Daguerre would not reveal the manipulatory details of his process until August. In 1841, Talbot announced his discovery of the calotype, or talbotype, process. This process reflected the work of many predecessors, most notably John Herschel and Thomas Wedgwood. In August 1841, Talbot licensed Henry Collen, the miniature painter (1798-c1872) as the first professional calotypist. Talbot's original contributions included the concept of a negative from which many positive prints can be made (although the terms negative and positive were coined by Herschel), and the use of gallic acid for developing the latent image. In 1842, for his photographic discoveries, which are detailed in his The Pencil of Nature (1844), he received the Rumford Medal of the Royal Society.

Whilst engaged in his scientific researches, he devoted much time to archaeology. He published Hermes, or Classical and Antiquarian Researches (1838-39), and Illustrations of the Antiquity of the Book of Genesis (1839). With Sir Henry Rawlinson and Dr Edward Hincks he shares the honour of having been one of the first decipherers of the cuneiform inscriptions of Nineveh. He was also the author of English Etymologies (1846).

In 1843-44, he set up an establishment in Baker Street, Reading, for the purpose of mass producing salted paper prints from his calotype negatives. The Reading Establishment (as it was known) also produced prints from other calotypist’s negatives and even produced portraits and copy prints at the studio.

He died in Lacock Abbey village, and is buried along with his wife and children in the churchyard there.
