David Thompson was a Canadian explorer, surveyor, and map maker of the early 1800’s. He is known as the greatest land geographer who ever lived. The natives of the North American continent knew him as Koo-Koo-Sint, “Star-Gazer”.
Born in England in 1770, he was poor and attended a charity school until the age of fourteen. Having shown an aptitude for mathematics he was apprenticed at this time to the Hudson’s Bay Company as a clerk and apprentice surveyor and left England for Canada, never to return.
While still in his apprenticeship he broke his leg badly and took two years to recuperate, during which he was stuck at the company headquarters. The company surveyor took this opportunity to teach the bright young man more about surveying skills, mathematics, reading the stars, and map making. Thompson showed great aptitude and learned his lessons well. After his training was over he went to work for Hudson’s Bay Company as a surveyor, but not liking the way the company did business he left a few years later and went to work for rival, North West Company, setting up trading posts, organizing men, and hiring native families to bring in furs.
Thompson took special pains with the Columbia River and its tributaries, mapping the basin from the source to the Pacific and claiming the Oregon territory for Britain. He explored what is now British Columbia, Alberta, Saskatchewan, Manitoba, Washington, Idaho, and Montana. Britain and America were engaged in a fierce struggle over territory during this period, and exploration and mapping were a big part of that struggle. Upon the news of the Lewis and Clark expedition, David Thompson was ordered to make explorations and surveys of the north western wilderness of the continent. Over the course of twenty-four years, from 1790 to 1814, he explored and accurately mapped 3.9 million square kilometers of North America, roughly a fifth of the continent, an absolutely astounding feat, particularly considering that his main job was to bring in the fur for the lucrative trade with England and the continent.
