(1933– ). A native of Switzerland who won the Nobel Prize in chemistry in 1991 for important methodological developments in NMR spectroscopy. He invented Fourier-transform NMR (FT-NMR), which multiplied sensitivity 10 to 100 times compared to dispersive instruments. He also devised two-dimensional NMR techniques, increasing resolution and enabling structure determinations of biologically important macromolecules. Ernst received his Ph.D from the Federal Technical Institute (ETH) in Zurich, Switzerland.
