Semyon Dezhnev (about 1605, Great Ustyug [1] - early 1673, Moscow) - Russian traveler, explorer, navigator, explorer of North and East Siberia, Cossack Ataman, the fur trader. The first known explorer, passed by the Bering Strait, connecting the Arctic Ocean to the Pacific and separating Asia and North America, Chukotka and Alaska, and did so for 80 years before Vitus Bering in 1648 [2]. It is noteworthy that the Bering failed to go all the Strait as a whole, and were restricted to swimming only in its southern part, whereas Dezhnev went strait from north to south, along its entire length.
