Nikolai
Nikolaevic Semenov was born in Saratov on April 3, 1896. He graduated from
Petrograd University in 1917 and in 1920 he took charge of the electron phenomena
laboratory of the Leningrad Physico-Technical Institute. He lectured at the
Polytechnical Institute and was appointed Professor in 1928. In 1931, he became
Director of the Institute of Chemical Physics of the U.S.S.R. Academy of Sciences
(which has moved to Moscow in 1943); from 1944 he has been a Professor at the
Moscow State University.
Semenov's outstanding work on the mechanism of chemical transformation includes
an exhaustive analysis of the application of the chain theory to varied reactions
and, more especially, to combustion processes. He proposed a theory of degenerate
branching which led to a better understanding of the phenomena associated with
the induction periods of oxidation processes. Semenov has made valuable contributions
to the field of molecular physics; he has also carried out investigations on
electron phenomena, dielectric breakdown and the propagation of explosive waves.
Semenov has written two important books concerned with his work. Chemical
Kinetics and Chain Reactions was published in 1934 with an English edition
in 1935. It was the first book in the U.S.S.R. to develop a detailed theory
of unbranched and branched chain reactions in chemistry. Some Problems of
Chemical Kinetics and Reactivity, first published in 1954, was revised in
1958; there are also English, American, German, and Chinese editions.
He became a Corresponding Member of the U.S.S.R. Academy of Sciences in 1929
and Academician in 1932: he was awarded five Orders of Lenin and the Order of
Red Banner of Labour. He is a member of the Chemical Society (London), Foreign
Member of the Royal Society, and foreign member of the American, Indian, German,
and Hungarian Academies of Sciences. He also holds Honorary Doctorate degrees
of Oxford and Brussels Universities, and since 1960 he has been Chairman of
the All-Union Society for Propagation of Political and Scientific Knowledge.
He married Natalya Nikolaevna Semenova; they have one son and one daughter.
