Richard R. Ernst

Richard Robert Ernst (14 August 1933 – 4 June 2021) was a Swiss physical chemist and Nobel laureate.

Ernst was awarded the Nobel Prize in Chemistry in 1991 for his contributions towards the development of Fourier transform nuclear magnetic resonance (NMR) spectroscopy while at Varian Associates and ETH Zurich. These underpin applications to both to chemistry with NMR spectroscopy and to medicine with magnetic resonance imaging (MRI).

He humbly referred to himself as a "tool-maker" rather than a scientist. Provided by Wikipedia
