Portrait of Ivan Papanin* on the background of the drifting polar station "North Pole"**.

Additional:

*Ivan Ivanovich Papanin (November 14, 1894, Sevastopol - January 30, 1986, Moscow) - Soviet Arctic explorer, Doctor of Geographical Sciences (1938), Rear Admiral (1943), twice Hero of the Soviet Union (1937, 1940).

**North Pole-1 (Russian: Северный полюс-1) was the first Soviet manned drifting station in the Arctic Ocean, primarily used for research.

North Pole-1 was established on 21 May 1937 and officially opened on 6 June, some 20 kilometres (12 mi) from the North Pole by the expedition into the high latitudes Sever-1, led by Otto Schmidt. The expedition had been airlifted by aviation units under the command of Mark Shevelev. "NP-1" operated for 9 months, during which the ice floe travelled 2,850 kilometres (1,770 mi). The commander of the station was Ivan Papanin. On 19 February 1938 the Soviet ice breakers Taimyr and Murman took four polar explorers off the station close to the eastern coast of Greenland. They arrived in Leningrad on 15 March on board the icebreaker Yermak.

The expedition members, hydrobiologist Pyotr Shirshov, geophysicist Yevgeny Fyodorov, radioman Ernst Krenkel, and the commander Ivan Papanin, were awarded the Hero of the Soviet Union title.
