Chebotarev, Aleksandr Stepanovich
Born Nov. 15 (27), 1881, in Belebei, in what is now the Bashkir ASSR; died Nov. 5, 1969, in Moscow. Soviet geodesist. Honored Worker in Science and Technology of the RSFSR (1947).
Chebotarev graduated from the Moscow Engineering Institute of Geodesy, Aerial Photography, and Cartography (formerly the Land Surveying Institute) in 1903. He became a professor there in 1921 and was the head of a subdepartment from 1922 to 1962. Chebotarev helped found the Central Scientific Research Institute of Geodesy, Aerial Photography, and Cartography. He developed a theory for equating traverse networks and leveling grids and applied methods of mathematical statistics and matrix calculus to the analysis of geodetic measurements. Chebotarev’s school of geodesy and mathematical analysis of measurements has received wide recognition both in the USSR and abroad. Chebotarev was awarded the Order of Lenin.
