Congratulations to John Fenn, Koichi Tanaka, and Kurt Wuerthrich for sharing the 2002 Chemistry Nobel. The common theme is characterization of proteins and other macromolecules, and the discoveries are (respectively) electrospray ionization for mass spectrometry, laser desorption for the same, and 2-D NMR techniques.

I'll write more on this tonight, but for what my opinion's worth, I'd say these are well-deserved accolades for some important techniques that otherwise wouldn't be as well recognized.
