Hugh Clapperton (18 May 1788 – 13 April 1827) was a Scottish traveller and explorer of West and Central Africa. He was born in Annan, Dumfriesshire, where his father was a surgeon. He gained some knowledge of practical mathematics and navigation, and at thirteen was apprenticed on board a vessel which traded between Liverpool and North America. After having made several voyages across the Atlantic Ocean, he was impressed for the navy, in which he soon rose to the rank of midshipman.
During the Napoleonic Wars he saw a good deal of active service, and at the storming of Port Louis, Mauritius, in November 1810, he was first in the breach and hauled down the French flag. In 1814 he went to Canada, was promoted to the rank of lieutenant, and to the command of a schooner on the Canadian lakes. In 1817, when the flotilla on the lakes was dismantled, he returned home on half-pay. In 1820 Clapperton removed to Edinburgh, where he made the acquaintance of Walter Oudney, who aroused his interest in African travel. Lieutenant G. F. Lyon, having returned from an unsuccessful attempt to reach Bornu from Tripoli, the British government determined on a second expedition to that country. Walter Oudney was appointed by Lord Bathurst, then colonial secretary, to proceed to Bornu as consul, accompanied by Hugh Clapperton.
