John BartramDied 22 Sep 1777 at age 78 (born 23 Mar 1699).American explorer and botanist who is also regarded as the father of American botany, a subject he self-taught from the age of ten. He made a systematic study of healing plants. In 1728, Bartram bought land beside the Schuylkill River at Kingsessing, outside Philadelphia, created Bartram's Garden, and began likely the first experiments in hybridizing in America. (His Garden now forms part of Philadelphia's small park system - the oldest living botanical garden in the U.S. - where many giant trees may still be seen that he planted.) He travelled widely to gather ripe seeds, roots and bulbs in proper condition for transplanting. Shipping many species to introduce in Europe developed into a business. His son William Bartram followed him as a naturalist.« |
