Wikipedia / Wikimedia Commons
Sir Alexander Mackenzie (c. 1764 – 12 March 1820) was a Scottish fur trader and explorer. In 1793, he became the first European to cross North America north of Mexico. A key figure in the North West Company, he aimed to push the company’s reach into western Canada and sell the furs gathered there in China. That ambition put him in competition with the monopolies held by the Hudson’s Bay Company and the East India Company. The Mackenzie River and Mount Sir Alexander bear his name.

- First recorded transcontinental crossing of North America north of Mexico (1793)
Lore & Background
Mackenzie was born in Stornoway, Lewis, the third of four children. At age 14, he sailed to New York City with his father in 1774. During the American War of Independence, his father and uncle served as lieutenants in the King's Royal Regiment of New York. For his safety as a son of loyalists, Mackenzie was sent to Montreal by 1778. By 1779, he had secured an apprenticeship with Finlay, Gregory & Co., a prominent fur trading company that merged with the North West Company in 1787.
On behalf of the North West Company, Mackenzie journeyed to Lake Athabasca and helped found Fort Chipewyan in 1788. In 1789, he set out by canoe on the river known to the Dene as the Dehcho (later named the Mackenzie River), reaching the Arctic Ocean on 14 July. In 1791 he returned to Britain to study longitude measurement. In 1792 he set out again, and on 20 July 1793 reached the Pacific coast at Bella Coola, British Columbia, completing the first recorded transcontinental crossing north of Mexico. He left a message painted on a rock near Dean Channel.
Reader's Guide
Mackenzie's significance lies in his 1793 crossing, which preceded the Lewis and Clark expedition by 12 years and demonstrated a viable transcontinental route through Canada. His explorations helped extend the Canadian fur trade westward and informed later efforts by Simon Fraser and David Thompson. The Mackenzie River, Mount Sir Alexander, Mackenzie Bay, and the municipality of Mackenzie, British Columbia, are named for him. His journals were published in 1801, and he was knighted in 1802. He served in the Legislature of Lower Canada from 1804 to 1808. His legacy includes schools named after him across Canada, a rose cultivar, and references in folk song and literature. The site of his 1793 inscription is now Sir Alexander Mackenzie Provincial Park and a National Historic Site. In 2016, he was named a National Historic Person.
