James Clark Ross

Sir James Clark Ross was a British naval officer and explorer remembered today for his exploration of the Arctic with his uncle Sir John Ross and Sir William Parry and, in particular, his own expedition to Antarctica.

Ross was born in London, the nephew of Sir John Ross, under whom he entered the navy in 1812, accompanying him on Sir Johns first Arctic voyage in search of a Northwest Passage in 1818. Between 1819 and 1827, Ross took part in four Arctic expeditions under Sir William Parry, and in 1829 to 1833, again served under his uncle on Sir Johns second Arctic voyage. It was during this trip that they located the position of the North Magnetic Pole onJune 1831 on the Boothia Peninsula in the far north of Canada. It was on this trip, too, that Ross charted the Beaufort Islands, later renamed Clarence Islands by his uncle.
