John Stewart Waugh (April 25, 1929 – August 22, 2014) was an American
chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe th ...

In mathematics, ergodicity expresses the idea that a point of a moving system, either a dynamical system or a stochastic process, will eventually visit all parts of the space that the system moves in, in a uniform and random sense. This implies th ...

[Wolf Foundation Prize Committee for Chemistry (n.d.)] Waugh was cited for his "fundamental theoretical and experimental contributions to high resolution nuclear magnetic resonance spectroscopy in solids."
In 2011, Waugh received th
Welch Award in Chemistryfor revolutionizing NMR spectroscopy. In the words of Ernest H. Cockrell, chair of th
Welch Foundation Waugh "discovered how to use NMR to study solids, creating a collection of tools that allows researchers to view the structures and properties of proteins, membranes, viruses, and many other critical components of life." His work continues to be used extensively in chemistry, physics, biology, materials science, and medicine. He died on August 22, 2014.
