The Nobel Prize in Chemistry 2002 was awarded for the development of methods for identification and structure analyses of biological macromolecules with one half jointly to John B. Fenn and Koichi Tanaka for their development of soft desorption ionisation methods for mass spectrometric analyses of biological macromolecules and the other half to Kurt Wüthrich for his development of nuclear magnetic resonance spectroscopy for determining the three-dimensional structure of biological macromolecules in solution.
