Vladimir Ivanovich Dal (alternatively transliterated as Dahl; Russian: Влади́мир Ива́нович Даль; November 10, 1801 – September 22, 1872) was one of the greatest Russian-language lexicographers and a founding member of the Russian Geographical Society. He knew at least six languages, including Turkic, and is considered one of the early Turkologists. During his lifetime he compiled and documented the oral history of the region that was later published in Russian and became part of modern folklore.
