Vladimir Ivanovich Vernadsky, also spelt Volodymyr Ivanovych Vernadsky (Russian: Владимир Иванович Вернадский; Ukrainian: Володимир Іванович Вернадський; 12 March [O.S. 28 February] 1863 – 6 January 1945), was a Russian, Ukrainian, and Soviet mineralogist and geochemist who is considered one of the founders of geochemistry, biogeochemistry, and radiogeology. He was one of the founders and the first president of the Ukrainian Academy of Sciences (now National Academy of Sciences of Ukraine). Vladimir Vernadsky is most noted for his 1926 book The Biosphere in which he inadvertently worked to popularize Eduard Suess's 1875 term biosphere, by hypothesizing that life is the geological force that shapes the earth. In 1943 he was awarded the Stalin Prize. Vernadsky's portrait is depicted on the Ukrainian ₴1,000 hryvnia banknote.
