Biography:
He was born on July 18, 1926 in the Kherson cityof Odessa province of the Ukrainian SSR.
In 1952 he graduated with honors from the Physics and Mathematics of N.K.Krupska Kherson State Pedagogical Institute where he entered in 1948.
In 1948 when he was a student N. K. Krupska Kherson State Pedagogic Institute, he restored saved by laboratory assistant physical office P. Bondar from hands of the Nazi invaders during World war USSR against Germany are being 2-inch refractor telescope that was placed before the war in astronomical pavilion which was a build by I. V. Levinson.
After graduation, he was left to work in the department as an assistant and he was asked to build a new observatory. This happened in 1958. On the recommendation of the director of Odessa astronomical observatory in V. P .Tsesevich academic institute observatory began systematic observations of variable stars, in which the active involvement of students of Physics and Mathematics. To research a 2-inch refractor was not enough. Therefore, in 1961 was acquired refractor telescope AVR-3 with a lens diameter of 130 mm and a focal length of 1950 mm. Pretty solid (total weight about 623 kg) instrument on German mount with clockwork allowed to carry out a visual observation and photography. There was a special cassette and screen plates 9h12 to observe the sun. Continued study of variable stars, the study was conducted covering the moon the stars and observe the planets and small bodies of the solar system. Later, led by Professor B.L.Shahanyan instead of tube refractor AVR-3 was found two tube. One was with achromaticity German Steinheil lens, an aperture of 136 mm and a set of points used for visual observations. Second was with English lens T.Cooke & Sons, aperture 141 mm, used for taking pictures on photographic plates.
During 1952-2000 he worked at the N. K. Krupskaya Kherson State Pedagogical Institute , first as an assistant, then senior lecturer at the Department of Higher Mathematics, Deputy Dean, twice elected dean of the Faculty of Physics and Mathematics (1968-1971; 1976-1979), he worked as head of the Department of Mathematical Analysis during 1971-1976, Associate Professor of Mathematical Analysis, Associate Professor of Physics.
In 1969 he defended his PhD "Study of red semi-regular variable stars in two colors".
In the 70's - 80's he was actively engaged in research on this issue "Study of all variable stars in the scattered galaxy cluster M-56", approved by the sector of variable stars of the Astronomical Council of the USSR Academy of Sciences, during which the search and study of photometric characteristics of 35 new variable stars. The second topic of the study "Study of the shape of the Earth" was approved by the group "Moon" of the USSR Academy of Sciences. Observations of the coverage of stars and planets by the Moon were carried out at the Institute Observatory for 5 years. According to the results of research, about 50 scientific papers were published in the "Reports of the Academy of Sciences of the USSR", "Reports of the Academy of Sciences of the Ukrainian SSR".
He was a member of the scientific and methodological council of the Yu. A. Gagarin Kherson Planetarium, conducted extensive lectures on the regional society "Knowledge", headed the section of physical and mathematical sciences and was a member of the board of this society.
For many years of fruitful work the scientist was awarded the medal "For Valiant Work in the Great Patriotic War", the badge "Excellence in Public Education of the Ukrainian SSR", diplomas and thanks of various levels, including a diploma of the Verkhovna Rada of the Ukrainian SSR. For successful fulfillment of socialist obligations he was awarded the badge "Winner of the socialist competition of 1974", the gold badge "For active work" of the All-Union Society "Knowledge".
He died on January 13, 2006.
