David FairchildBorn 7 Apr 1869; died 6 Aug 1954 at age 85. David Grandison Fairchild was an American botanist and plant explorer who supervised the introduction of over 20,000 exotic plants and varieties of established crops into the U.S., including soya beans, mangos, alfalfa, nectarines, horseradish, and flowering cherries. He spent 37 years seeking new and useful plants by travelling the world including the South Sea Islands, Australia, New Zealand, New Guinea, Japan, China, the Persian Gulf, Africa, the West Indies, and South America. In 1898 he set up a small plant introduction garden on a six-acre plot near Miami, Florida, especially interested in aesthetically valuable or economically useful exotic fruits and plants. He managed the Foreign Seed and Plant Introduction program of the U.S. Dept. of Agriculture (1906-28).« |
