John TorreyDied 10 Mar 1873 at age 76 (born 15 Aug 1796).American botanist and chemist known for his extensive studies of North American flora. The first professional botanist in the New World, Torrey published extensively on the North American flora, advocated the "natural system" of classification that was replacing Linnaeus' artifical system, and collaborated for many years with his student Asa Gray (who was to become an important botanist). Torrey never was able to make a living from botany and worked (among other things) as a freelance chemical analyst. Unidentified plants collected on government expeditions to the western states were sent to him for study, however, as a foremost authority of his time. A genus of evergreen trees, Torreya, is named for him. |
