Baffin, William 1584-1622. English explorer and navigator. In 1616, he and Robert Bylot explored Baffin Bay, NE Canada, and reached latitude 77 degrees 45' N, which for 236 years remained the `furthest north'. In 1612, Baffin was chief pilot of an expedition in search of the Northwest Passage, and in 1613-14 commanded a whaling fleet near Spitsbergen, Norway. He piloted the Discovery on an expedition to Hudson Bay lead by Bylot in 1615. After 1617, Baffin worked for the East India Company and made surveys of the Red Sea and Persian Gulf. In 1622 he was killed in an Anglo-Persian attack on Hormuz.
