Joseph Rock's Images
Updated 2004-06-08.

The following photographs were taken by the botanist and explorer Joseph Rock, now deceased. They were scanned and put online at Harvard University Visual Information Access. Unfortunately, that database's interface borders on the unnavigable, and the denial of search engines to the site does not do justice to these amazing shots. Thus, I have liberated them with this alternative interface! The shots were taken during the 1920s in western China.  Rock also collected photographs for the US Department of Agriculture and the Smithsonian Institution.

Rock was also a cartographer. Some maps of his are available here, chopped in to sections. I have glued the Lijiang map together, and it is available as a single, large image (~2MB) here.

For additional information about the final (largest) group of  images, or to receive permission for use, please contact the Arnold Arboretum of Harvard University 125 Arborway, Jamaica Plain MA 02130 or by e-mail hortlib@oeb.harvard.edu. You can visit the South Central China and Tibet: Hotspot of Diversity web site to learn more about Joseph Rock as well as current research in the region.

For more information on Rock's character, check out his colleague Peter Goullart's book, Forgotten Kingdom.

Rock's Naxi Manusript collection was purchased by the American Library of Congress, who have digitised a selection of the manuscripts and put them online.  A couple of additional photographs by Rock were also available on that site, and have been added below as the second group of two photographs.
