Biography
Richard Robert Ernst (14 August 1933 – 4 June 2021) was a Swiss physical chemist who changed nuclear magnetic resonance spectroscopy and won the Nobel Prize in Chemistry in 1991. Born and raised in Winterthur, Switzerland, Ernst studied at ETH Zurich, where he later returned as a professor after working in industry. His pioneering work greatly advanced chemical analysis and medical diagnostics by developing Fourier transform nuclear magnetic resonance (NMR) spectroscopy.
Ernst's scientific journey started at Varian Associates in California, where he worked from 1963 to 1968. There, he developed the principles of Fourier transform NMR, significantly enhancing the sensitivity and efficiency of NMR measurements. This innovation allowed scientists to analyze complex molecular structures more precisely and quickly. His work laid the groundwork for magnetic resonance imaging (MRI), one of the key diagnostic tools in modern medicine.
After returning to Switzerland in 1968, Ernst joined the faculty at ETH Zurich and continued to improve NMR techniques. He developed two-dimensional NMR spectroscopy, which made it possible to determine the three-dimensional structures of biological molecules like proteins. This breakthrough expanded our understanding of biological processes at the molecular level and had a major impact on structural biology and biochemistry.
Throughout his career, Ernst received many international awards besides the Nobel Prize, including the Marcel Benoist Prize in 1985, the Wolf Prize in Chemistry in 1991, and the Louisa Gross Horwitz Prize in 1991. He was made a Foreign Member of the Royal Society in 1993 and received honorary doctorates from institutions like the École polytechnique fédérale de Lausanne, the University of Antwerp, and Babeș-Bolyai University. Despite his many awards, Ernst remained humble about his work, often describing himself as a "tool-maker" rather than a scientist, highlighting his focus on creating instruments and methods for other researchers to make discoveries.
Before Fame
Ernst grew up in Winterthur during the 1930s and 1940s. Switzerland stayed neutral during World War II, while scientific progress in physics and chemistry picked up speed worldwide. He attended ETH Zurich in the 1950s, at a time when nuclear magnetic resonance was still fairly new, having been discovered by Felix Bloch and Edward Purcell in 1946.
During the 1950s and early 1960s, the progress of NMR spectroscopy was slowed by technical issues that made it difficult to use, as measurements were time-consuming and lacked sensitivity. Ernst saw these problems early in his career and worked on developing mathematical and instrumental solutions to make NMR more practical and useful for scientific research.
