Georgy Konstantinovich Danilov (; 10 January 1897 – 29 July 1937) was a Soviet linguist, Africanist and polyglot. He was executed during the Great Purge and rehabilitated during the Khrushchev Thaw. Early years and education Georgy Konstantinovich Danilov was born on 10 January 1897 in Chyhyryn, a city located in the Chigirinsky Uyezd of the Kiev Governorate of the Russian Empire (present-day Cherkasy Oblast of central Ukraine). He was of Russian ethnicity. Danilov enrolled at Moscow University(ИФФ МУ,Faculty of engineering and physics) in 1916 but was immediately drafted into the Imperial Army and sent to the front during World War I for a period of two years. Although he formally graduated, his education remained incomplete. In 1922 he returned to Moscow, where he was assigned to the department of languages at the Communist University of the Toilers of the East (or Коммунистический университет трудящихся Востока КУТВ). He worked at КомА (Коммунистическая академия, Communist Academy), then taught high school.
