John William Hill or often J.W. Hill was a British-born American artist working in watercolor, gouache, lithography, and engraving. Hill's work focused primarily upon natural subjects including landscapes, still lifes, and ornithological and zoological subjects. In the 1850s, influenced by John Ruskin and Hill's association with American followers of the Pre-Raphaelite Brotherhood, his attention turned from technical illustration toward still life and landscape.
