William Matthew Hart

English illustrator and lithographer who worked for the English ornithologist John Gould. He began working for Gould in 1851 making the patterns for the lithographic stones for Gould’s monumental work, A Monograph of the Trochilidae, or Family of Hummingbirds. Thus started an association that was to last thirty years. By 1870 Hart had become Gould's chief artist and lithographer.
