Edward G. Mazurs Collection of Periodic Systems Images

This collection predominantly consists of lantern slides and transparencies of models of the periodic table used by Edward G. Mazurs in the production of his book Graphic Representations of the Periodic System During One Hundred Years. The collection includes models by Dmitri Mendeleev, Edward Janet, and other notables, as well as Mazurs himself, and effectively provides a panorama of the evolution of the periodic table in the one hundred years following Mendeleev's initial 1869 design. Alternative layouts for the table include circular, cylindrical, pyramidal, spiral, and triangular forms ranging in date from the 1860s to the 1950s, with the bulk of the images dating from the 1880s to the 1920s.
