John S. Waugh

John Stewart Waugh was an American chemist and Institute Professor at the Massachusetts Institute of Technology, born on April 25, 1929. He is known for developing average Hamiltonian theory and using it to extend nuclear magnetic resonance spectroscopy, previously limited to liquids, to the solid state. He is the author of ANTIOPE, a freeware general purpose Windows-based simulator of the spectra and dynamics of nuclear magnetic resonance, and he also used systems of a few coupled spins to illustrate the general requirements for equilibrium and ergodicity in isolated systems. In 1974 he was elected a member of the National Academy of Sciences in the Chemistry section, and he was awarded the Wolf Prize in Chemistry for 1983 and 1984 with Herbert S. Gutowsky and Harden M. McConnell for independent work on NMR spectroscopy. He died on August 22, 2014.
