The cover of John Herschel's (1792-1871) copybook that accompanied his talk to the Royal Society of London, on March 15, 1839. The book, titled on the cover 'Specimens of Photography to accompany Sir John Herschel's Paper', contains photographs by Herschel from 1839 and a sketch of his father, William Herschel's (1738-1822) reflecting telescope taken from an original photograph. Herschel became increasingly interested in photography and was a strong and vocal proponent for its use in astronomy, believing there should be no conflict between science and art.
