Jason Dean, Cataloger & Technical Services Librarian at Crystal Bridges Museum of American Art (and previously a volunteer at the research library here at the Amon Carter), recently told the fascinating story of The North American Sylva; or, a Description of the Forest Trees of the United States, Canada, and Nova Scotia . . . This signal illustrated botanical work by François André Michaux (1770–1855) and Thomas Nuttall (1786–1859) stands as the most important study of American trees before the twentieth century, offering an unparalleled record of species growing in the United States and Canada during the period. As Jason points out, this work not only combines the research of both authors but also offers the opportunity to study two different illustration techniques: early engravings (with hand-coloring) based on illustrations by the famous French flower painter Pierre-Joseph Redouté (1759–1840) and later hand-colored lithographs. Crystal Bridges has the 1841 edition (Philadelphia: J. Dobson, 1841) while the Amon Carter has the 1859 edition (Philadelphia: D. Rice & A. N. Hart, 1859). The Amon Carter's copy was acquired on the occasion of Ruth Carter Stevenson’s 80th birthday.
