Dmitry Nikolayevich Ushakov (ru|Дмитрий Николаевич Ушаков; 24 January 1873 – 17 April 1942) was a Russian philologist and lexicographer.[1]
He was the creator and chief editor (1935–1940) of the 4-volume Explanatory Dictionary of the Russian Language with over 90,000 entries. He was also the creator of an orthographic dictionary of the Russian language (1934).[1]
He influenced his student, Grigoriy Vinokur, who dedicated his book The Russian Language: A Brief History to him.[2]
Ushakov died in Tashkent, where he had been evacuated to during World War II.[1] His work on a definitive explanatory dictionary of the Russian language was continued by Sergei Ozhegov.
