1800–1877
A key pioneer of early photography, he developed the calotype process, which made it possible to create multiple prints from a single negative. His experiments helped shape photography into both a practical technology and an artistic medium.

by William Henry Fox Talbot
Born in Dorset in 1800, William Henry Fox Talbot was an English scientist, inventor, and scholar whose curiosity ranged across mathematics, chemistry, languages, and archaeology. He is most widely remembered for his work in the 1830s and 1840s, when he helped lay the foundations of modern photography.
Talbot's most important breakthrough was the calotype, an early photographic process that used a paper negative to produce multiple positive prints. That was a major advantage over one-of-a-kind images such as daguerreotypes, and it gave photography a reproducible future. He also developed the salted paper process and later worked on photomechanical reproduction.
His photographs of windows, books, plants, architecture, and everyday objects showed that the new medium could be used for science, record-keeping, and art at the same time. Talbot died in 1877, but his experiments remain central to the story of how photography began.
