1911 Encyclopædia Britannica/Mackenzie, Sir Alexander
MACKENZIE, SIR ALEXANDER (c. 1755-1820), Canadian explorer, was probably a native of Inverness. Emigrating to North America at an early age, he was for several years engaged in the fur trade at Fort Chippewyan, at the head of Lake Athabasca, and it was here that his schemes of travel were formed. His first journey, made in 1789, was from Fort Chippewyan along the Great Slave Lake, and down the river which now bears his name to the Arctic Ocean; and his second, made in 1792 and 1793, from Fort Chippewyan across the Rocky Mountains to the Pacific coast near Cape Menzies. He wrote an account of these journeys, Voyages on the River St Lawrence and through the Continent of North America to the Frozen and Pacific Oceans (London, 1801), which is of considerable interest from the information it contains about the native tribes. It is prefaced by an historical dissertation on the Canadian fur trade. Amassing considerable wealth, Mackenzie was knighted in 1802, and later settled in Scotland. He died at Mulnain, near Dunkeld, on the 11th of March 1820.
