John Fenn, Koichi Tanaka, and Kurt Wu¨thrich will receive the 2002 Nobel Prize in Chemistry for helping to develop tools for the study of large biological molecules. Fenn, a professor of chemistry at Virginia Commonwealth University in Richmond and professor emeritus of Yale University, and Tanaka, an R&D engineer with Shimadzu Corp in Kyoto, Japan, will share half of the prize for “their development of soft desorption ionization methods for mass spectrometric analyses of biological macromolecules.” Wu¨thrich, a professor of molecular biophysics at ETH Zu¨rich, will receive the other half for “his development of nuclear magnetic resonance spectroscopy for determining the three‐dimensional structure of biological macromolecules in solution.”
