Originally published as a serial between 1844 and 1846, The Pencil of Nature was the first book to be illustrated entirely with photographs. Early enthusiast William Henry Fox Talbot hoped to spur public interest in photography but was forced to cease publication after just six installments. In its time, the serial was not a commercial success; however, more than 165 years later, it is recognized as a major contribution to the history of photography. Indeed, it has been said that the importance of this book is comparable to that of the Gutenberg Bible in the history of printing. In 1840 Fox Talbot invented the Calotype process—the precursor to film cameras—transforming everyday subjects into works of art. His twenty-four resulting prints, which include architectural studies, local landscapes, still lifes, close-ups, and even a carefully executed portrait, remain strikingly modern and quietly beautiful.
