Stepan Petrovich Krasheninnikov (; – ) was a Russian explorer of Siberia, naturalist and geographer who gave the first full description of Kamchatka in the early 18th century. He was elected to the Russian Academy of Sciences in 1745. The Krasheninnikov Volcano on Kamchatka is named in his honour. Early life Krasheninnikov was educated in the Slavic Greek Latin Academy of Moscow (1724–32), where Lomonosov was his class-mate. As part of Vitus Bering’s extensive preparations for the Second Kamchatka Expedition, 12 students from the academy were selected as potential student interns or assistants for the professors – Krasheninnikov being one of them. Thus, he furthered his education in St Petersburg before embarking upon the Second Kamchatka Expedition (1731–42). The Second Kamchatka Expedition Krasheninnikov was to study plants, animals and minerals, but in addition he developed a strong interest in Siberian history and geography. During the early part of the expedition, he accompanied professor Gmelin on the travel through the Urals and western Siberia to Yeniseysk. He made numerous observations of natural history, ethnology and linguistics, e.g. records of Evenki (tungus) and Buryat vocabulary. From Bering’s headquarters at Yakutsk, the expedition professors Gmelin and Gerhard Friedrich Müller sent Krasheninnikov ahead to Okhotsk and Kamchatka to build house and make preliminary observations. Thus, he became the member of the expedition with the most extensive knowledge of the peninsula. He published his observations in 1755 ("Описание земли Камчатки"; English translation by James Grieve (1764) as History of Kamtschatka). However, he drew extensively on the manuscripts of the deceased Georg Wilhelm Steller. Apart from detailed accounts of the plants and animals of the region, there also were reports on the language and culture of the indigenous Itelmen and Koryak peoples, with whom he is said to have got along extremely well. Later life Krasheninnikov spent ten years on the Second Kamchatka Expedition. On his return to St Petersburg, he wrote and defended his doctoral thesis on ichthyology in 1745. He was appointed adjunct at the Academy of Sciences, and later head of the Academy's Botanic Garden and professor of natural history at the university. He was one of only 26 Russians to become Academy members in the 18th century. In 1752, Krasheninnikov went on his last expedition to the tracts of Lake Ladoga and Novgorod to investigate the flora. He died before being able to publish his observations, which instead were published by David
