Soviet geologist, geographer, outstanding traveler, corresponding member of the USSR Academy of Sciences, son of V.A. Obruchev. 
Born in Irkutsk, in 1902, the family moved to Tomsk, where Obruchev graduated from a real school. From an early age he participated in geological expeditions led by his father: in 1905 in the Frontier Dzungaria, 1906 - in the Semirechye, 1909 - in the Semipalatinsk province. There were no doubts about the choice of profession - in 1910, Obruchev entered the Physics and Mathematics Faculty of Moscow University, which he successfully completed in five years. 
He worked consistently in the Geological Committee (1917–1929), in the Yakut Commission of the USSR Academy of Sciences (1929–1932), in the All-Union Arctic Institute (1932–1941), in the Institute of Geological Sciences of the USSR Academy of Sciences (1941–1950). Obruchev's last place of work was the Precambrian Geology Laboratory of the USSR Academy of Sciences, which he headed in 1963. 
The main works of Obruchev are related to the study of the geology and geomorphology of Eastern Siberia and the North-East of the USSR. 
In 1917–1924 he conducted geological studies on the Central Siberian Plateau, largely contributing to the discovery of the Tunguska coal basin; in 1926–1935 explored the basins of Indigirka and Kolyma, establishing their gold content. Obruchev first proposed to combine the mountain structures of the middle course of Indigirka and Kolyma called the Chersky Range and developed a tectonics scheme for Northeast Asia. In 1937-1954 He studied Eastern Sayan, Khamar-Daban and North-Eastern Tuva.

Obruchev is the author of a number of popular science books and articles, including “Into Uncharted Territories”, “Over the Mountains and Tundras of Chukotka”, “In the Heart of Asia”, “Mysterious Stories” and others, as well as the literary study “Over Lermontov's Notebooks”. He compiled the "Handbook of the traveler and local historian".
