"Robert Hunt (1807 - 1887) was a librarian keeper of mining records at the Museum of Practical Geology and professor of mechanical engineering at the Royal School of Mines, at London. He carried on numerous photographic and photomechanical experiments and he was one of the founders of the London Photographic Society. These experiments with organic and inorganic light-sensitive substances, which, with characteristic unselfishness, he made public during the early forties of the last century, were extremely useful in the study of photochemistry, which was then in its infancy, and were of great service for years to those who came after him and used his researches for the basis of their studies." Eder- HISTORY OF PHOTOGRAPHY p. 326.

"Included are reports on Hunt's earliest experiments on solar energy and its effect involving both vegetation and metallic salts or compounds. An introductory chapter on the discoveries of Daguerre and Fox Talbot is exceedingly useful as it establishes the range of various light sensitive materials applicable to photography, including platinum, iron and antimony. His is the first use of the word 'platinotype' with reference to platinum prints. The book as a whole is one of the most crucial and one of the earliest theoretical treatises on the science, and differs slightly from the later, 1854 edition, except in some more recent discoveries." From the Arno Press description THE LITERATURE OF PHOTOGRAPHY. In truth, this second edition was largely rewritten and greatly expanded to include a great many advances in the medium in the ensuing ten years.

The copy of J [James] B [Booker] B [Blake] Wellington, 1858 - 1939, an English scientist and photographer. He worked with George Eastman in New York before becoming a director at Kodak and later he set up his own photographic materials and publishing company, Wellington & Ward. He was a member of the Linked Ring Brotherhood.
