Biography:
He was born in June, 26, 1909 in the Irkutsk city Irkutsk province of the Russian Empire.
In 1937 graduated from East Siberian University in Irkutsk city.
In 1937-1938, astronomer-magnetologist participated in the work of the first research station "North Pole", which drifted in the polar ice since May 1937 to February 1938.
During 1939-1941 he worked as an assistant, senior teacher of the East Siberian University, and later also the director of the Observatory of the East Siberian University.
On his initiative, visual observations of the Sun began using the Zeiss refractor at the city observatory.
During 1941-1944 he participated in the Great Patriotic War USSR against Nazi Germany, which was part of World War II.
During 1944-1947 he studied at the graduate school of Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR.
During 1944 - 1959 he worked at the Poltava gravimetric observatory of the Academy of Sciences of the Ukrainian SSR initially as a research fellow, and then the academic secretary.
In 1947 he defended his Ph.D. thesis on the topic "Theory of motion of the Earth's poles". The work was carried out under the supervision of O. Ya. Orlov at the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR.
In 1949-1959 he performed latitudinal observations on the Bamberg zenith telescope at the Poltava Gravimetric Observatory according to a program he developed himself.
After a detailed analysis of the results of observations at stations of the International Latitude Service for 1900-1935, he obtained for the major semiaxis of the ellipse nutation value 9.197″, which contradicts the conclusions of classical theory of Earth's rotation, which is based on the assumption of its absolute hardness. Together with Yevtushenko E. I. on the basis of the analysis of more than 200 thousand instantaneous latitudes received at stations of the International Latitude Service, established that the semiaxes of the elliptical crescent are equal to 0.096″ and 0.093″, while the classical theory of the Earth's rotation gives them values of 0.088″ and 0.081″.
In 1957, he defended his doctoral thesis "Nutation and forced movement of the Earth's poles according to the data of latitudinal observations" at the Main Astronomical Observatory of the Academy of Sciences of the USSR (Pulkovo urban village).
In 1959, the astronomer returned to the Main Astronomical Observatory of Academy of Sciences of the Ukrainian SSR.
During 1955 - 1961, he was president of the Commission to study the motion of the poles of the Earth of the International Astronomical Union. Investigates the Earth's rotation, the motion of the poles of the Earth. In 1956-1960, the scientist first developed the theory of nutation for an absolutely elastic Earth in the first time in the world and determined the parameters of nutation according to astronomical observations of latitudinal changes. In the problem of developing the theoretical foundations for constructing coordinate systems in outer space, he solved a number of questions on the relationship of the radiointerferometric and equatorial coordinate systems and the determination of the parameters of rotation of the Earth's rotation parameters.
During 1959 - 1973 he worked as the director of the Main astronomic observatory of the Academy of Sciences of the Ukraimian SSR.
In March 1963, the scientist took part in the Second Assembly of the International Committee for the International Year of the Calm Sun. During this trip, it was agreed that the Ukrainian Academic Observatory will serve as one of two international comet research data centers.
Since 1969 he was a full member of the Academy of Sciences of the Ukrainian SSR. The Academician received the title in several techniques: the Academy chose him as his member, and the Central Committee of the CPU did not approve of the election, demanding that he join the Communist Party. But eventually he was elected an academic, although he did not join the party.
Since 1973 he has worked at the Main astronomical observatory Academy of Sciences of the USSR as head of the department of fundamental astrometry, and since 1979 was a consultant.
During 1967-1975 he was the editor-in-chief of the Ukrainian interagency magazine "Astrometry and Astrophysics".
In 1983 he was among the co-sponsors of the State Prize of Ukraine in the field of science and technology for the cycle of work "Development of the theory and practical construction of coordinate systems for geodynamic, selenodezic and space research".
He died November 8, 1986 in Kiev City.
The main directions of his scientific work are astrometry, the study of patterns of rotation of the Earth, the movement of the poles of the earth and the change of latitudes as well as nuclear physics.
