Meyer (1875-1918), U.S. Department of Agriculture (USDA) plant explorer from 1902 to 1918. The materials were collected by Isabel S. Cunningham during research for her book, Frank N. Meyer: Plant Hunter in Asia. In April 2006, Cunningham donated more of her research notes, articles, photographs, and a first edition annotated copy of Frank N. Meyer: Plant Hunter in Asia.
