Rudolph A. Marcus redefined science with his Marcus theory, which explained electron transfer reactions and thus threw light on reactions such as photosynthesis. The Canadian-American chemist won a Nobel Prize for his work and also contributed to the transition-state theory. He now teaches at Singapore’s Nanyang Technological University.
John Charles Polanyi is a Hungarian-Canadian scientist, who won the Noble Prize in Chemistry for his contribution to the dynamics of chemical reaction. He developed a technique called infrared chemiluminescence, which helped him to study the exchange of chemical bonds and detail how the excess energy is removed during chemical reactions.
German-Canadian physicist Gerhard Herzberg is remembered for his Nobel Prize-winning work on ascertaining the electronic structure of molecules, particularly free radicals. He had escaped to Canada following the rise of the Nazis and later also worked in the U.S. His doctoral students included Japanese chemist Takeshi Oka.
Maud Menten was a Canadian bio-medical and medical researcher. She made several important contributions to enzyme kinetics and histochemistry. She studied medicine at the University of Toronto, becoming among the first women in Canada to earn a medical doctorate. She collaborated with Leonor Michaelis to come up with the Michaelis-Menten equation model.
Nobel Prize-winning Canadian-American chemist Henry Taube is best remembered for his research on electron-transfer reactions. Apart from teaching at reputed institutes such as Cornell and Stanford, Taube also became a member of the National Academy of Sciences. He was also an ardent fan of classical music and loved gardening, too.
Ronald Gillespie was a British chemist who specialized in the field of molecular geometry. Gillespie, who moved to Canada in 1958, is credited with instituting inorganic chemistry education in Canada. Ronald Gillespie was the recipient of several prestigious awards and honors, such as the Keith Laidler Award, the Henry Marshall Tory Medal, and the Canadian Centennial Medal.
