Luther Burbank (Wikipedia)
Luther Burbank (March 7, 1849 – April 11, 1926) was an American botanist, horticulturist and pioneer in agricultural science. He developed more than 800 strains and varieties of plants over his 55-year career. Burbank’s developments included those of fruits, flowers, grains, grasses, and vegetables. He developed (but did not create) a spineless cactus (useful for cattle-feed) and the plumcot.
