Catharine FurbishDied 6 Dec 1931 at age 97 (born 19 May 1834).American botanist who spent sixty years meticulously collecting, classifying and drawing the flora of Maine increased the scientific knowledge of the state, and contributed to a number of botanical collections. She began this work in 1870, and extensively traveled the state for 38 years. She enthusiastically explored the depths of wilderness areas to discover new specimens. The exquisite, accurately detailed watercolor drawings she made of the collected specimens were highly regarded by academic botanists. In 1895, she helped found the Josselyn Botanical Society of Maine. She described her fieldwork in American Naturalist in 1881, 1882 and 1901. Her watercolor drawings have been preserved in the 16 folio volumes she gave to Bowdoin College Library in 1908.« |
