Early Life and Education
Richard R. Ernst was born in 1933 in Winterthur, Switzerland, and came of age in a country where physics and chemistry were already shaped by pioneers such as Felix Bloch. After schooling in his hometown, he entered the Swiss Federal Institute of Technology in Zurich (ETH Zurich), where he found his intellectual home for much of his life. He earned a diploma in chemistry in the late 1950s and completed a doctorate in physical chemistry at ETH Zurich in 1962. His doctoral work was conducted under the guidance of Hans H. Gunthard, a leading figure in molecular spectroscopy at ETH. In Gunthard's environment, Ernst learned the interplay of theory, instrumentation, and rigorous experimentation that would characterize his own approach to research.

Formative Years in American Industry
In 1963 Ernst moved to the United States to join Varian Associates in Palo Alto, then the global hub for innovation in nuclear magnetic resonance. At Varian he worked closely with Weston A. Anderson and colleagues on ways to increase the sensitivity and speed of NMR experiments. Out of this period came the decisive turn toward pulsed excitation and signal averaging, and the introduction of Fourier transform methods into routine NMR measurements. The combination of short, well-defined radiofrequency pulses with digital data acquisition and Fourier analysis multiplied the power of NMR, enabling spectra that had previously taken impractically long to record. These advances were not isolated inventions; they were embedded in a culture of teamwork in which engineers and chemists were brought into direct conversation. Ernst absorbed that culture of practical precision and brought it back to Europe.

Return to ETH Zurich and Building a School
Ernst returned to Switzerland in 1968 and rejoined ETH Zurich, where he rose through academic ranks and eventually became professor of physical chemistry. Over the next decades he built an internationally influential laboratory that married instrument development with methodological innovation. Drawing on ideas circulating among NMR physicists and chemists, he and his coworkers transformed the conceptual toolbox of the field. A pivotal step was the development of two-dimensional NMR, which offered a window into couplings and correlations that could not be separated in conventional one-dimensional spectra. The conceptual seeds of 2D NMR had been articulated by Jean Jeener at a summer school, and Ernst's group provided the practical and mathematical framework to make the approach broadly usable.

One landmark of this era is the 1976 publication with Walter P. Aue and Enrico Bartholdi that laid out the principles of two-dimensional spectroscopy and demonstrated their power for chemical analysis. The work showed how carefully designed pulse sequences and phase-cycling schemes could disentangle interactions in complex molecules. It led to experiments such as COSY and other correlation methods that quickly became routine across chemistry and later biology. Ernst's laboratory attracted and trained a generation of spectroscopists who carried these techniques to research groups around the world. Among close colleagues who extended and disseminated these ideas were Geoffrey Bodenhausen and Alexander Wokaun, with whom Ernst later coauthored a widely used reference work that organized the theory and practice of one- and two-dimensional NMR.

Networks of Collaboration and Influence
Ernst's scientific life unfolded within a dense network of collaborators, students, and colleagues. At Varian, Weston A. Anderson provided an industrial research context in which Fourier techniques could be tested on real instruments. Back at ETH Zurich, Walter Aue and Enrico Bartholdi were key partners in translating theoretical proposals into experimentally robust sequences. The presence of Kurt Wuthrich at ETH gave a biological focus to the expanding repertoire of NMR methods. Wuthrich's adoption of multidimensional NMR for proteins, carried out with his own students and postdoctoral researchers, showed how Ernst's pulse and processing approaches could reveal the architecture of complex biomolecules in solution. This interplay between method developers and application-oriented groups exemplified Ernst's belief that spectroscopy advances by solving real structural and dynamical problems.

The broader NMR community also shaped, and was shaped by, Ernst's contributions. He built upon foundations laid by pioneers like Edward Purcell, Felix Bloch, and Erwin Hahn, whose discoveries of nuclear induction and spin echoes defined the physical principles of the field. In turn, Ernst's emphasis on pulsed excitation and Fourier analysis helped make possible the later explosion of magnetic resonance imaging, developed by Paul Lauterbur and Peter Mansfield, who showed how gradient fields and reconstruction could produce images of the human body. While MRI advanced in a distinct direction, it relied on the same core ideas of signal acquisition and transformation that Ernst had normalized for spectroscopy.

Scientific Style and Contributions
Ernst was known for a style that fused mathematical clarity with empirical rigor. He insisted that pulse sequences be specified completely, that phase cycling and coherence pathways be accounted for, and that every claim be anchored in data. He promoted the use of Fourier transform methods not as a mere computational trick but as a way to recast experimental design: excite broadly, acquire efficiently, and decode the information with mathematical tools. He advocated systematic approaches to sensitivity enhancement, signal-to-noise optimization by averaging, and careful calibration of instrumentation. This mindset informed the development of two-dimensional and later higher-dimensional experiments that became essential in analyzing molecular structure, conformational dynamics, and reaction intermediates.

His coauthored textbook with Geoffrey Bodenhausen and Alexander Wokaun provided a coherent formalism for practitioners, organizing the field at a time when the proliferation of pulse sequences risked fragmentation. Through lectures, courses, and meticulous publications, he trained scientists to think in terms of spin dynamics, operator formalisms, and practical compromises imposed by real machines. Many of those who passed through his orbit went on to establish leading laboratories, thereby propagating his methodological DNA across continents.

Recognition and Service
The breadth and depth of Ernst's impact were recognized globally. In 1991 he received the Nobel Prize in Chemistry for his contributions to the development of high-resolution NMR spectroscopy, especially the introduction of Fourier transform methods and the advancement of multidimensional techniques. In his communications around the award, he emphasized the collective character of scientific progress and acknowledged the roles of collaborators such as Weston A. Anderson, Walter Aue, and Enrico Bartholdi, and the broader lineage that reached back to Bloch and Purcell.

At ETH Zurich he shouldered responsibilities that extended beyond his own laboratory, helping to maintain the institution's prominence in physical chemistry and instrumentation. He participated in international advisory committees, supported scientific societies, and served on editorial and conference boards that shaped standards of experimental practice. His name became associated with precision in the design of experiments and fairness in the attribution of credit, values that he promoted in his mentorship and public talks.

Personal Interests and Later Years
Outside the laboratory, Ernst cultivated broad interests that included the arts and culture, reflecting a curiosity that did not recognize strict boundaries between scientific and humanistic pursuits. Colleagues recall a person who balanced exacting standards with a generosity toward young researchers, encouraging them to master both the theory and the craft of their work. In retirement he maintained ties to ETH Zurich and to the international NMR community, continuing to lecture and to engage in discussions about the future of instrumentation and methodology. He remained a point of contact for former students and collaborators spread from Switzerland to North America and Asia, who viewed him as a touchstone for clarity and intellectual integrity.

Legacy
Richard R. Ernst died in 2021 in Switzerland, leaving behind a transformed field and a widely distributed network of scientists whose careers were shaped by his ideas and mentorship. His legacy is inscribed in the instruments and pulse programs of every NMR laboratory, in the standard curricula that teach Fourier and multidimensional methods, and in the everyday practice of chemists and biophysicists who decipher complex structures by techniques his work made reliable. The pathways from spin dynamics to practical spectra that he helped devise continue to underpin innovation, whether in new probes and magnets, in hyperpolarization strategies, or in the integration of NMR with complementary methods. The scientists around him during his long career, mentors like Hans H. Gunthard, industrial partners like Weston A. Anderson, coauthors such as Walter Aue, Enrico Bartholdi, Geoffrey Bodenhausen, and Alexander Wokaun, and colleagues like Kurt Wuthrich, mark out a collaborative map that mirrors the reach of his influence. In the history of twentieth-century physical chemistry, Ernst stands as a central figure who turned NMR into a universally accessible, exquisitely sensitive window on molecular reality.
