George McClelland Whitesides is an American chemist and professor of chemistry at Harvard University. He is best known for his work in the areas of nuclear magnetic resonance spectroscopy, organometallic chemistry, molecular self-assembly, soft lithography, microfabrication, microfluidics, and nanotechnology. A prolific author and patent holder who has received many awards, he received the highest Hirsch index rating of all living chemists in 2011.

John Dombrowski Roberts was an American chemist. He made contributions to the integration of physical chemistry, spectroscopy, and organic chemistry for the understanding of chemical reaction rates. Another characteristic of Roberts' work was the early use of NMR, focusing on the concept of spin coupling.
