SEMENOV, NIKOLAI NIKQLAEVICH (Physical Chemist) 



N. N. Semenov was born April 15, 1896. In 1917 he gradu- 

 ated from Petrograd University. During the years 1920-31, he 

 worked at the Leningrad Physico-Technical Institute. He be- 

 came Chief of the Institute of Chemical Physics of the U.S.S.R. 

 Academy of Sciences in 1931 and subsequently the Director. In 

 1928 he was made professor at the Leningrad Polytechnic Insti- 

 tute and in 1944 professor at the Moscow University. He was 

 a Corresponding Member of the U.S.S.R. Academy of Sciences 

 from 1929 until 1932 when he was elected Academician. In 1947 

 he became a member of the Communist Party of the Soviet 

 Union. He was awarded a Stalin Prize in 1941, and in 1956 the 

 Nobel Prize. 



Semenov' s first scientific work was in molecular physics 

 and electron phenomena such as: vapor condensation on solid 

 surfaces, the ionization of vapors of salts under the influence 

 of an electron bombardment, and electric breakdown of di- 

 electrics. And he also developed a thermal theory of the di- 

 electric breakdown. The initial assumptions of this theory 

 were utilized by Semenov in his theory of thermal explosions of 

 gas mixtures. According to this theory, the cause of the ex- 

 plosion is the unattainment of the heat equilibrium during
