...chemistry award went to two Americans, Charles J. Pedersen, 83, now retired from Du Pont, and Donald J. Cram, 68, of the University of California, Los Angeles, and French Chemist Jean-Marie Lehn, 48. The three were cited for their work, dating back as far as the 1960s, in creating artificial molecules that can mimic the behavior of hormones and other organic substances. The lone winner in medicine was Susumu Tonegawa, 48, a Japanese-born molecular biologist at M.I.T. His contribution: showing how a handful of genes in a small number of immune cells turn out a staggering variety...
...just won the Nobel Prize for Chemistry. Reason: Cram is in the rug-shampooing business. The Swedish Academy of Sciences had rung up the wrong man. Quipped UCLA Chemist Donald J. Cram after hearing about the mix-up: "There is some chemistry involved in carpet cleaning." Cram, Pedersen and Lehn, working independently, shared the award for their work in "host-guest" chemistry. "The basis of our work," explains Lehn, "is the way molecules are able to recognize each other." In nature, molecules that work together have complementary shapes, like a lock and a key, and only the right key will...
Cram, Pedersen, and Lehn were recognized for their pioneering work in synthesizing molecules that can aid in separating radioactive and non-radioactive tissues and purifying molecules...

...essence of the work was the discovery of crown-ethers made by Pedersen several years ago," said Frank B. Baird, Jr. Professor of Science Dudley R. Herschbach, who won the Nobel Prize in chemistry last year. "Cram and Lehn were among the leaders in following up Pedersen's work...
