The iconic 19th-century painter and naturalist John James Audubon explored the American frontier in search of "the feathered tribes" he loved and studied. A self-taught artist and ornithologist, Audubon left a legacy of art and science that made him famous in his lifetime and endures to this day. His portrait hangs in the White House, his statue stands over the entrance to the American Museum of Natural History, and his name was adopted by the nation's first conservation organization.About 1820 Audubon... [see more] decided to make a comprehensive study of North American birds. He traveled widely in the American South, drawing every known species and adding new ones. His large, life-sized watercolors represented both artistic innovations and scientific contributions, but he had to go abroad to find subscribers to support his publication. Audubon's major work, The Birds of America, was published in several editions. Beginning in 1827 a large folio of engravings was produced in England, followed by smaller, more popular editions-including both text and illustrations-that appeared in the United States into the 1870s. His study of mammals, The Viviparous Quadrupeds of North America, completed by his sons and long-time collaborator John Bachman, also was produced in two sizes and several editions between 1845 and 1854.
