William Henry Fox Talbot (18001877) was a British pioneer in photography, yet he also embraced the wider preoccupations of the Victorian Age-a time that saw many political, social, intellectual, technical, and industrial changes. His manuscripts, now in the archive of the British Library, reveal the connections and contrasts between his photographic innovations and his investigations into optics, mathematics, botany, archaeology, and classical studies. Drawing on Talbot's fascinating letters, diaries, research notebooks, botanical specimens, and photographic prints, distinguished scholars from a range of disciplines, including historians of science, art, and photography, broaden our understanding of Talbot as a Victorian intellectual and a man of science.
