William Atherton DuPuy was a well-known naturalist who wrote anecdotally and personally about nature in ANIMAL FRIENDS AND FOES, INSECT FRIENDS AND FOES, THE NATION'S FORESTS, and PLANT FRIENDS AND FOES. In another vein he authored GREEN KINGDOM, his account of the life of a forest ranger, and controversially produced HAWAII AND ITS RACE PROBLEM. He also wrote for Harper's and had a connection with the Department of the Interior and, less happily, with the military's chemical warfare projects.
