Rock Honorary Research Associate Far Eastern and Russian Institute University of Washington is one of the great explorers of the last half of the 20th century. He "was first sent to China in the early 1920s by the United States Department of Agriculture U.S.D.A. to collect seeds of a tree that later were used in the treatment of leprosy. His explorations resulted in the introduction of conifers rhododendrons 493 species potentilla and primula to the U.S. Nonetheless biographer Hubert Rhodes wrote in 1956 that Rock's collection process - collecting all plants not just searching for exotics - had important implications and opened possibilities for reforestation in North America's severest northern climates. Rock also introduced blight-resistant chestnuts. He deposited a sizable collection of birds and mammals at the U.S. National Museum the Arnold Arboretum and Harvard's Museum of Comparative Zoology. During his later years botanizing back in Hawaii in the 1950s Rock noted ominously that many native species he had collected earlier in his career had vanished completely . His efforts in linguistics are widely recognized; he spent years collecting and translating 8000 volumes of original Naxi literature including their religious tracts" Hunt Botanical Institute website.
