April 6, 1919–November 25, 1997
BY RICHARD J. FIELD AND JOHN A. SCHELLMAN
RICHARD MACY NOYES WAS an exceptionally fine physical chemist who dedicated his abundant personal and intellectual abilities to making the world a better place for his having been a part of it. He directed his scientific work almost entirely toward understanding the details of how chemical reactions occur; making seminal contributions in isotopic-exchange processes, the theory of molecular diffusion in solution, and treatment of complex kinetics and reaction mechanisms; and most memorably, pioneering work on the mechanisms of oscillating chemical reactions and nonlinear dynamics in chemistry. He participated actively in public affairs, mainly through protection of the natural world he loved, promotion of international cooperation, and in administrative and leadership roles at the University of Oregon, where he spent many happy and productive years. His goodwill, integrity, and intelligence were highly valued and respected by all who met him.
Dick was born in Champaign, Illinois, on April 6, 1919, the first child of William Albert Noyes, Sr., and Katharine Haworth (Macy) Noyes. He was the third of four surviving children of his father, then nearly sixty-two years old and chairman of the Department of Chemistry at the University
