navigator whose exploration of the Bering Strait and Alaska prepared the way for a Russian foothold on the North American continent.

After a voyage to the East Indies, Bering joined the fleet of Tsar Peter I the Great as a sublieutenant. In 1724 the tsar appointed him leader of an expedition to determine whether Asia and North America were connected by land, because Russia was interested both in colonial expansion in North America and in finding a northeast passage—i.e., a sea route to China around Siberia. (In 1648 a Russian, Semyon Dezhnyov, had sailed through the Bering Strait, but his report went unnoticed until 1736.) On July 13, 1728, Bering set sail from the Siberian peninsula of Kamchatka and in August passed through the Bering Strait into the Arctic Ocean. Bad weather prevented thorough observation, and, though he did not sight the North American coast, he concluded that Siberia and America were not joined.

During the reign of Empress Anna, Bering sought to undertake a second expedition. His simple plan, however, was expanded into Russia's Great Northern Expedition (1733–43), which mapped much of the Arctic coast of Siberia. On June 4, 1741, Bering sailed from Kamchatka in the St. Peter, joined by Aleksey Chirikov commanding the St. Paul. A storm later separated the ships, and Chirikov went on to discover several Aleutian Islands independently. Bering sailed into the Gulf of Alaska on August 20. Anxious to get his ship back to safety, he was able to reconnoitre only the southwestern coast, the Alaska Peninsula, and the Aleutian Islands. Suffering from scurvy, he was unable to maintain effective command, and the ship was wrecked early in November on the shore of Bering Island, near Kamchatka. After his death there, a few survivors were able to reach Siberia and brought news of excellent fur-trading possibilities in the Aleutians and Alaska.
