Richard R. Ernst, a Swiss chemist who won the Nobel Prize in 1991 for his work refining nuclear magnetic resonance, or N.M.R., spectroscopy, the powerful method of chemical analysis behind M.R.I. technology, died on June 4 in Winterthur, in northern Switzerland. He was 87.
The Swiss Federal Institute of Technology Zurich (ETH Zurich), where Dr. Ernst had spent almost his entire career, announced the death on its website. No cause was given.
Dr. Ernst — whose work and interests spanned chemistry, physics, math, music and art — helped develop N.M.R. from a niche, time-intensive technique into a critical scientific tool routinely used in local hospitals and undergraduate chemistry labs.
As a chemist he was pre-eminent.
“To compare him to Einstein would offend physicists,” said Jeffrey A. Reimer, an N.M.R. expert at the University of California, Berkeley. “But in terms of his impact in the discipline, Ernst is foundational.”
