Semenov, Nikolai Nikolaevich

This challenge was met by Russian chemist Nikolai Nikolaevich Semenov (1896-1986), working in St. Petersburg, and, independently, English chemist Cyril Norman Hinshelwood (1897-1967) at Oxford. In 1928 they each developed the concept of a branched chain reaction to account for the kinetics of these explosions and their strange dependence on pressure and temperature. 

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.
