Mistaken for Grasses. Supported by an $80,000 grant from the U.S. Agriculture Department, which was concerned about the possibility that the disease might spread to the U.S., Harpaz finally identified the virus carrier as a tiny plant hopper named Delphacodes striatellus. The insect, he discovered, was not particularly fond of corn, preferring the sap of barley, wheat and oat plants during winter and wild grasses in the summer. But while moving from its winter-to summer-plant hosts, the plant hopper frequently plunged its stylet into young corn seedlings in the mistaken belief that they were wild grasses...
Spraying seedlings with chemicals to control the plant hopper would have been prohibitively costly. Instead, Harpaz turned to the virus itself. Further research revealed that it was extremely sensitive to heat, ceasing all reproductive activity within the plant hopper when the temperature reached 76°F. To Harpaz, this suggested a simple solution: instead of in early April, hybrid corn should not be sown in Israel until late May. Thus when the seedlings emerged early in June, he reasoned, the few viruses left in the plant hoppers' salivary glands would be too sluggish to infect the corn...
...hulking (6 ft. 4 in.) son of a Nyack, N.Y., merchant was always a loner. He devoured Tolstoy and Turgenev in high school, went to New York at 17 to study at the New York School of Art with Robert Henri, a leader of the Ashcan School. Hopper learned there that the proper study of American artists is American daily life, but the dark, flamboyant style that Henri encouraged among Hopper's fellow students, most notably George Bellows and Rockwell Kent, was not for Hopper. Instead, he went on to Paris, absorbed the lighter palette of the impressionists...
Something That Suggests. Hopper sold his first painting, a canvas called Sailing, for $250 in the 1913 Armory Show. But popularity was slow in coming. It was not until 1923, after an agonizing decade during which he did commercial illustrations, that he sold his second. By the 1930s he had achieved a measure of success; his oils were being bought by the Metropolitan Museum, and his realism was accepted as the quintessence of the search for American roots and the often angry realism of Depression-era artists. Last March he was named the keystone artist to represent America...
