'''Feodosy Nikolayevich Krasovsky''' ({{langx|ru|Феодосий Николаевич Красовский}}; {{OldStyleDate|26 September |1878|14 September}} – October 1, 1948) was a Russian and Soviet [[astronomer]] and [[geodesist]].<ref>p.25, Farbman</ref> He was born in [[Galich, Russia|Galich]]. In 1900 he graduated from the ''Mezhevoy'' (land surveying) ''Institute'' in [[Moscow]]; in 1907 he began working as a lecturer there.<ref>p.496, Gillispie</ref>
==Research work== At the end of 1928 the ''[[Central Research Institute of Geodesy, Aerial Surveying and Cartography]]'' (TsNIIGAiK) was founded on his initiative; he worked there as a director (1928–1930) and as a deputy director of science (1930–1937). Between 1924 and 1930 Krasovsky headed astronomical, [[geodesy|geodetical]] and [[cartography|cartographical]] works in the Soviet Union. He worked out the theory and methods of construction of the national geodetical network of the USSR and solved related problems of [[topography]] and [[gravimetry]] works.<ref>Guelke</ref> Krasovsky and another Soviet geodesist, Aleksandr Aleksandrovich Izotov, in 1940 defined dimensions of an [[ellipsoid]] which was named the [[SK-42 reference system|Krasovsky ellipsoid]] and was later used as a [[reference ellipsoid]] in the [[Soviet Union]] and other countries until the 1990s.<ref>p.464, The American Congress on Surveying and Mapping</ref>
In 1939 Krasovsky became the Corresponding Member of the [[Academy of Sciences of the Soviet Union]].
Krasovsky died in [[Moscow]] in 1948.
