Chemical kinetics: The study of how fast chemical reactions occur and how their rates depend on conditions. This field framed Hinshelwood’s investigations of reaction rates and mechanisms.
Nikolay Semenov: A Russian physical chemist who developed theories of chain reactions and shared the 1956 Nobel Prize in Chemistry. He shared the prize with Hinshelwood for research on chemical reaction mechanisms.
University of Oxford: A university in Oxford, England, with a history dating to the eleventh century. Hinshelwood studied chemistry there and later held its Dr Lee’s Professorship.
Chemical Society of Japan: A Japanese professional society founded in 1878 to advance chemistry. Hinshelwood received its prestigious award for contributions to chemistry.
Reaction mechanism: The sequence of elementary molecular events by which reactants become products. Hinshelwood used kinetic evidence to infer the steps underlying observed reactions.
Ernest Rutherford: A New Zealand-born physicist who pioneered nuclear physics and led research at the University of Manchester and Cambridge. Hinshelwood studied under Rutherford at the University of Manchester during the First World War.
University of Manchester: A public research university in Manchester, England, formed in its modern incarnation in 2004. Hinshelwood completed wartime research there under Ernest Rutherford.
Copley Medal: The Royal Society’s oldest medal, awarded for outstanding achievements in scientific research. Hinshelwood received the medal in 1962 for his contributions to physical chemistry.
Chain reaction: A reaction sequence in which reactive intermediates generate further reactive intermediates. His Nobel-recognized work helped establish how chain processes can govern reaction behavior.
Frederick Lindemann: A British physicist and scientific adviser who became a prominent figure in government and wartime science. Lindemann supported Hinshelwood’s early research career at Oxford.
