Ferdinand Wrangell, baron, a Russian traveller, born in Esthonia about 1795, died in Dorpat, June 6, 1870. He was a naval officer, and in 1820-'23 commanded a sledge expedition to the Polar sea, N. of East Siberia, in conjunction with Anjou. They penetrated to I at. 72° 2' N., and reported an open sea in the distant north. In 1825-'7 he made a voyage round the world. From 1829 to 1834 he was governor of Russian America, and subsequently he held office in the navy department at St. Petersburg till 1849, when the Russian American company chose him as director. In 1854 he returned to the navy department as chief of the hydrographical division; in 1858 he was adjoined to the imperial council with the rank of admiral and general aide-de-camp. An account of his arctic expedition was prepared in German by Engelhardt (2 vols., Berlin, 1839), after the traveller's diaries, and in 1840 was translated into English by Mrs. Sabine, under the title of "Wrangell's Expedition to the Polar Sea in 1820-'23." A fuller narrative was published in Russian (2 vols., St. Petersburg, 1841). In 1867 Capt. Long, in traversing the part of the Polar sea navigated by the Russian explorer, discovered a large tract of land, which Wrangell had endeavored to reach, and which is called after him Wrangell Land.
