DORODNITSYN, ANATOLII ALEKSEEVICH (Hydrodynamicist) 



A. A. Dorodnitsyn was born December 2, 1910. In 1931 he 

 graduated from the Groznenskii Petroleum Institute. Since 

 1936 he has been teaching and carrying out work in higher edu- 

 cational and scientific institutions of Moscow and Leningrad. 

 He started working in 1941 at the Central Aerodynamic Insti- 

 tute. From 1944 to 1955 he worked at the Mathematical Insti- 

 tute of the U.S.S.R. Academy of Sciences, and in 1955, he was 

 appointed Director of the Computer Center of the U.S.S.R. 

 Academy of Sciences now the Institute of Cybernetics. Dorod- 

 nitsyn was made professor in 1947 at the Moscow Physico- 

 Technical Institute. He has been an Academician of the U.S.S.R. 

 Academy of Sciences since 1953. In 1946, in 1947, and in 1951, 

 he was awarded Stalin Prizes. 



The investigations of Dorodnitsyn deal with problems of dy- 

 namic meteorology, aerodynamics, and applied mathematics. 

 His study of the influence of uneven land surfaces on air 

 streams is very important. He explained theoretically the for- 

 mation of descending currents over mountain ridges. He is 

 concerned with a study of boundary strata in compressible gas 

 and supersonic flows of compressible gas; he also studied 

 asymptotic behavior of derivatives of several classes of non- 

 linear differential equations. 



As of 1961, Dorodnitsyn was Chairman of the Commission 

 on Computing Techniques of the U.S.S.R. Academy of Sciences. 



In June 1958, Dorodnitsyn visited the United States to attend 

 a Conference on Digital Computers at Michigan University.
