Alexander Mackenzie (1764-1820)
Sir Alexander Mackenzie (or MacKenzie, Scottish Gaelic: Alasdair MacCoinnich, 1764 – 12 March 1820) was a Scottish explorer. He is known for his overland crossing of what is now Canada to reach the Pacific Ocean in 1793. This was the first east to west crossing of North America north of Mexico and preceded the Lewis and Clark expedition by 10 years.
