Nikolai Marr

Nikolai Yakovlevich Marr (, ''Nikolay Yakovlevich Marr''; , ''Nikoloz Iak'obis dze Mari''; — 20 December 1934) was a Georgian-born historian and linguist who gained a reputation as a scholar of the Caucasus during the 1910s before embarking on his "Japhetic theory" on the origin of language (from 1924), now considered as pseudo-scientific, and related speculative linguistic hypotheses.

Marr's hypotheses were used as a rationale in the campaign during the 1920–30s in the Soviet Union of introduction of Latin alphabets for smaller ethnicities of the country. In 1950, the "Japhetic theory" fell from official favour, with Joseph Stalin denouncing it as anti-Marxist. Provided by Wikipedia
