James Leon Williams was a doubly talented photographer. As an artist who was heavily influenced by the compositional precepts of Peter Henry Emerson (1856–1936) he was acclaimed for his photogravure picture books, "The Home and haunts of Shakespeare" (1892), and "The land of Sleepy Hollow and the home of Washington Irving" (1887). As a scientist, his photographic studies confirmed the theory of a causal relationship between acid-forming bacteria and tooth enamel demineralisation under the plaque biofilm. That his images can be found illustrating the papers and textbooks of other researchers, not just his own, is testament to his stature as a histologist. Appalled that students of American dental schools lacked the materials to study enamel formation or dental bacteria in situ, Williams personally funded these institutions with his photomicrographs. Today he is remembered for his pioneering work in prosthodontics, conducted with Alfred Gysi (1865-1957).
