Sylvanus Charles Thorp Hanley
About
Sylvanus Charles Thorp Hanley (1819–1899) was a British conchologist and malacologist who published the first book on shells using the then new technique of photography. He authored Conchologia indica with William Theobald which was a treatise on the shells of British India. The plates were drawn and lithographed by George Brettingham Sowerby the younger, who was well known for writing and illustrating excellent works of natural history, especially conchological works. Sowerby became the best illustrator of conchological works of his time, illustrating such classics as Reeve's monumental twenty-volume Conchologia Iconica.
