Flemish merchant and explorer who established trade between the Low Countries and Russia and explored the northern coast of Russia while searching for a route to China and the East Indies.

The first Flemish navigator of the Arctic Ocean, Brunel sailed beyond Lapland in 1565 in search of a northeast route to China. After establishing a trading post at the mouth of the Northern Dvina River (now Arkhangelsk, Russia), he was imprisoned by the Russian government. He was released (1566?) through the intervention of the Stroganovs (Stroganov Family), a wealthy Russian merchant family, for whom he went to work. As their agent he established regular trade between Russia and the Netherlands (1570). By 1578 the Netherlands' commercial sphere of influence spread over the entire White Sea region, and a Dutch settlement was founded on the present site of Arkhangelsk.

Continuing his search for a northeastern passage, Brunel was the first western European to make an overland trip from Moscow to the Ob River in Siberia, in 1576. He set sail with one ship in 1581 on an Arctic expedition that ended when the ship was wrecked in Pechora Bay after unsuccessfully attempting to sail through the Yugorski Straits into the Kara Sea. In 1584 he made another attempt to find a northeast route but was drowned when his ship capsized in the Pechora River.
