CHEMISTRY NOBEL IS SHARED BY 3; 2 WIN IN PHYSICS
Date: Thursday, October 15, 1987 The Royal Swedish Academy of Sciences gave the chemistry award to Donald J. Cram, chemistry professor at the University of California at Los Angeles; Charles J. Pedersen, a former research chemist at the Du Pont Co.; and Jean- Marie Lehn, a chemistry professor at the Universite Louis Pasteur in Strasbourg, France. Named to receive the top prize for physics were Georg Bednorz of West Germany and K. Alex Mueller of Switzerland. They were the first to discover ceramic materials that can conduct electricity with virtually no loss of energy at unusually high temperatures. "It really shakes me up," Cram, a 68-year-old native of Brattleboro, Vt., told radio station KNX-AM in Los Angeles. "What I'm delighted about is that the two people with whom I'm sharing it are very fine people." Pedersen, 83, reached at his home in Salem, N.J., told reporters: "I've never had an experience like this. It is a great honor." Pedersen, who is retired and suffers from Parkinson's disease, was pleased that the honor came during his lifetime, said Herman Schroeder, former director of research for Du Pont and a close family friend. Lehn, 48, speaking from his Strasbourg laboratory, said he was "a bit surprised, but very pleased." Pedersen, Cram and Lehn were recognized for discovering some of the mechanisms by which organic molecules recognize and fit into one another ''like a key fits a lock," academy officials said. The work of the three has enormous implications in biology and medicine, since all natural enzymes catalyze important biochemical reactions by recognizing and binding to other molecules in the body. The findings of Bednorz and Mueller sparked a feverish race among scientists worldwide to find other compounds that are superconducting at ever higher temperatures. Previous metal superconductors worked only at extremely cold temperatures, limiting them to a few expensive, esoteric uses.
Practical superconductors may make possible a broad range of applications, "It's a great day for me," a smiling Mueller, 60, told reporters in Naples, where he was participating in a physics symposium. "I felt like I was in the clouds, like my feet were not touching the ground," Bednorz, 37, said at a news conference at the International Business Machines Corp. laboratory in Switzerland. This is the second straight year that the physics prize has gone to scientists from IBM's Zurich lab. Last year, IBM's Gerd Binnig and Heinrich Rohrer shared the prize with a West German scientist for designing the scanning tunneling microscope. It is also the third consecutive year that a German has won or shared the physics prize and the second that an American has shared the chemistry prize. Each Nobel carries a prize of $340,000, which is divided among the laureates in each field. In announcing the chemistry award, the academy said the work by Cram, Pederson and Lehn "laid the foundation for what is today one of the most active and expanding fields of chemical research" -- an area known as ''supramolecular chemistry." A crucial part of the body's defense system, for instance, is the ability of antibodies to recognize invading agents such as bacteria or viruses, which can then be destroyed by other molecules in the immune system. But scientists do not yet know exactly how such molecules recognize and bind to each other to stop the spread of disease. American scientists have been represented overwhelmingly among the winners of Nobel Prizes since they were first awarded in 1901. US citizens have won 52 of the 129 physics awards and 31 of the 86 chemistry prizes. Superconductivity itself has a long Nobel Prize history. It was discovered in 1911 by the Dutch physicist Heike Kamerlingh Onnes, who received the Nobel Prize in 1913. But in recent years, progress in the field, which focused primarily on metallic compounds, had been maddeningly slow. "I think a lot of people in this field are delighted that Bednorz and Mueller won," said Robert J. Cava, a member of the team at AT&T Bell Laboratories who has also pursued new superconducting compounds. "They did the breakthrough thinking and we're all following the path that they laid out for us." BASS ;10/14 LDRISC;10/15,15:10 NOBEL15
