Hinshelwood, Sir Cyril, 70, retired since 1965 as professor of chemistry at Oxford University, died Oct 9 1967 in London. Sir Cyril, who was a fellow of the Royal Society and its president... 

HINSHELWOOD, SIR CYRIL N. (1897-1968). An English chemist who won the Nobel prize for chemistry in 1956 along with Nikolay Semenov, a Russian. He authored The Kinetics of Chemical Change." The Structure of Physical Chemistry." and many other journal articles. His work clarified inorganic and organic reactions. He was educated at Oxford before he began lecturing and research. 

Hinshelwood, Sir Cyril Norman (1897-1967) English chemist who, simultaneously with Nikolay Semenov, investigated chemical reaction kinetics in the interwar years, for which they shared the Nobel Prize in chemistry in 1956. He was a linguist and classical scholar, and was president of the Royal Society.

Stability and dynamics of chemical reactions within batch systems date back to the pioneering work of Russian scientist Nikolay Semenov on chain reactions and combustion, for which he shared the 1956 Nobel Prize with Sir Cyril Hinshelwood. There have since been considerable literature contributions, the most widely studied system being the irreversible first order reaction A B with Arrhenius kinetics k T) = kot p —E/RT). The mass balance (in dimensionless variables) within the reactor yields ...

The Nobel Prize was not awarded for the discovery of chain reactions. However, in 1956, Sir Cyril Norman Hinshelwood from Great Britain (1897-1987, London) and Nikolai Nikolaevich Semenov from Russia (1896, Saratov, to Moscow, 1986) were jointly awarded the Nobel Prize for (mostly) developing branched chain reactions. The first monograph on chain reactions was written by Semenov. 

Sir Cyril Norman Hinshelwood, Academician Nikolai Nikolaevich Semenov. More than half a century has elapsed since the first Nobel Prize in Chemistry was awarded to van t Hoff for his discovery of the laws of chemical dynamics. Some of the greatest advances in chemical kinetics since that time have emerged from your researches and they have inspired a great number of scientists to continued fruitful studies. Your results are of equally great importance to technology and to the more theoretical aspects of chemistry. 

The Nobel lecture of Sir Cyril Hinshelwood has an entirely different character and stmaure. Semenov analyzes step-by-step developments and describes chemical details of the chain processes, placing an emphasis on contributions of more than a dozen Russian scientists who would become, in the course of time, world authorities. Sir Cyril s presentation has a rather philosophical character, although it is titled Chemical kinetics in the past few decades. Particularly, some elementary reactions (such as Hj + O2) and their general significance were presented. He also described the importance of collaboration of scientists, saying ... 

Sir Cyril Norman Hinshelwood s early studies of molecular kinetics led to the publication of Thermodynamics for Students of Chemistry and The Kinetics of Chemical Change in 1926. He studied the explosive reaction of hydrogen and oxygen and described the phenomenon of chain reactions. Hinshelwood was jointly awarded the Nobel Prize in Chemistry in 1956 for his research into the mechanisms of chemical reactions.
