William Henry Harvey (February 5, 1811 - May 15, 1866) was an Irish botanist and phycologist. Harvey was an authority on algae and bryophytes (mosses). In 1844 Harvey became curator of the Trinity College Herbarium and in 1848 Professor of Botany of the Royal Dublin Society. In 1853 he made a 3 year voyage, visiting South Africa, Ceylon, Australia, New Zealand, Tonga, Fiji, and Chile. Stock Photo
