**Background**

In 1927 Dorodnitsyn graduated from high school in Grozny.

In 1931 he graduated from the Grozny Oil Institute, specializing in "Maintenance Engineer oil."

In 1936, Anatoly entered the graduate school of the Main Geophysical Observatory (Leningrad), where he studied until 1938.

In 1939 Dorodnitsyn defended his thesis for the degree of Candidate of Physical and Mathematical Sciences on the topic: "Some problems of the earth`s surface irregularities of airflow."

October 23, 1953, bypassing the rank of Corresponding Member, Academy of Sciences of the USSR was elected to the Department of Physics and Mathematics, specialty Geophysics.

Since 1941 to 1960, Anatoly worked at the Central Aerohydrodynamic Institute as senior engineer, head of department, head of sector, Deputy Chief, the scientific head of the laboratory.

In 1942 Dorodnitsyn defended his thesis for the degree of Doctor of Technical Sciences on the topic: "The boundary layer in a compressible gas."

C 1945 to 1955 Dorodnitsyn worked at the Mathematical Institute of the USSR Academy senior researcher and head of the department.

In 1949 - awarded the academic title of professor.

He was among the founders of the Computing Center of the USSR, now - Computing Centre of. Dorodnitsyn the Russian Academy of Sciences. In 1955 he became the first director of the Computing Center.

C 1955 to 1989, Anatoly is Director of the Computing Center of the USSR.

From 1989 to 1994 he worked as an honorary director and scientific director of the Computing Center of USSR Academy of Sciences.

Anatoly died on June 7, 1994 in Moscow.

The main scientific works are devoted to Dorodnitsyn ordinary differential equations, algebra, meteorology, swirl wing theory, the theory of the boundary layer in a compressible gas, a supersonic gas dynamics, numerical method of integral relations, the small parameter method for the Navier-Stokes equations. Considerable attention is also paid Anatoly various aspects of computer science.

Start Dorodnitsyn received the following results:

I study the question of the asymptotic behavior of solutions of some classes of nonlinear differential equations.

Developed the vortex theory of wings of complex shapes, suggested methods for calculating axisymmetric supersonic gas flows.

Developed numerical method of integral relations for solutions of equations in partial derivatives and methods for the numerical solution of the Navier-Stokes equations.

He gave a theoretical description of the air currents over the mountain ranges. To construct a theory of the boundary layer in a compressible gas.

Anatoly Dorodnitsyn thrice been awarded the Stalin Prize. In 1946 - for research in the field of aerodynamics of the aircraft at high flight speeds, in 1947 - for the development of new projects of high-speed aircraft wings, in 1951 - for research in the field of aerodynamics.

In 1970 Dorodnitsyn awarded the title Hero of Socialist Labor, the Order of Lenin and the gold medal "Sickle and Hammer" for his great contribution in the development of Soviet science and the training of specialists in the field of geophysics and applied mathematics, and in connection with his sixtieth birthday. In 1981 byd awarded the Prize of the USSR Council of Ministers for the establishment of the first stage of computer-aided design of complex engineering products. In 1983 he was awarded the Lenin Prize for his work in the field of computer technology.

Also, AA Dorodnitsyn was awarded five Orders of Lenin (1956, 1959, 1963, 1970, 1980), the Order "Badge of Honor" (1943), the Order of the Red Star (1945), the Order of the Red Banner of Labor (1954), Order of the October Revolution (1975) and the Order Friendship of peoples (1982) and numerous medals, including the medal "For valiant labor in the Great Patriotic war of 1941-1945.", medal "in commemoration of the 800th anniversary of Moscow", silver medal of Paris. Jubilee Medal "For valorous work. To commemorate the 100th anniversary of Vladimir Lenin`s birth ", the medal" 25 years of scientific cooperation of the GDR Academy of Sciences and the USSR Academy of Sciences ", medal" Century of the Bulgarian Academy of Sciences ", medal of the Mongolian Academy of Sciences, a commemorative medal to them. Chelomei.

Dorodnitsyn was twice awarded the Prize. Krylov Ukrainian Academy of Sciences, in 1972 - for a series of works on asymptotic methods of solving the van der Pol equation and some other classes of differential equations, and in 1978 - for a series of papers on numerical methods for aerodynamics in 1983 awarded the prize to them. Glushkov for the series of works "Development of machine-oriented data processing techniques", published from 1976-1982.
