Early Years of David Thompson

David Thompson was born in 1770 in London to David and Ann Thompson. His father died when he was very young, and due to financial problems, his mother had to place David and another brother in the care of the Grey Cook Hospital for underprivileged children. While there, David studied math, navigation, and surveying, where he excelled and graduated. Joining the Royal Navy, he received further schooling in math, trigonometry, geometry, and the use of nautical instruments. By 1784, at age 14, the Grey Coast paid the Hudson Bay Company five pounds for David to serve as an indentured servant for seven years as a clerk.

David would go on to become one of the greatest land geographers of the world. His life was hard, and he started in poverty, made many important discoveries, and mapped more of Canada and the northwest of America than anyone. Later in his life, he ended up ill and again in poverty but what he gave to Canada and the United States was immeasurable.

He would receive a high honor by the Canadian government and be named a NATIONAL HISTORIC PERSON in 1927.

Thompson Sails to North America

Sailing on May 1784 from London, David arrived in Manitoba, Canada, in September. For several years he worked in Saskatchewan and then in the Manchester House by 1787. He broke his tibia about this time, and while recuperating, he studied math, astronomy, and surveying under Phillip Turner. His indenture time was coming to an end, and instead of receiving the usual gift of clothing on departure, he requested surveying tools. He hired on with the Hudson Bay Company whereby 1794, he was promoted to a surveyor, and he worked there until 1797. Thompson discovered Athabasca Pass, a mountain pass between Alberta and British Columbia. His maps were so accurate they would be used for over one hundred years.

David was determined to be a surveyor, not just a fur trader, so he left Hudson Bay Company and walked eighty miles to the North West Fur Company. Immediately he was hired and tasked to survey the boundary along the water route from Lake Superior to Lake of the Woods. In 1804 the company made him a full partner. Sometime in 1806, he was sent to find a route to the Pacific Ocean to open trading in the northwest. Crossing the Rocky Mountains in 1807, he explored and mapped the Columbia River basin.

And David successfully explored and mapped over 1.5 million miles, and he did this by horse, canoe, dog sled, and on foot. One of the maps David made was given to the North West Company in 1814 and is now housed in Ontario, Canada. The map covered 1.5 million miles.

Thompson and the Columbia River

During the year 1799 David married Charlotte Small, a thirteen year old Metis, daughter of a Scottish fur trader and a Cree mother. Together they would have thirteen kids and remain married for 57 years. Charlotte proved to be invaluable to David. She was able to speak the language with the natives and traveled with David even with the children. David was called Koo-Koo-Sint or 'Stargazer' by the natives.

One of David's biggest contributions was his exploration and mapping the entire length of the Columbia River. He was the first to explore the Columbia. David had spent 34 years exploring and mapping.

David Thompson's Later Life

After years of exploring and mapping, David and his wife retired to Quebec. His sight was failing, and he was unable to finish his memoirs from his 77 notebooks. It was J.B. Tyrrell who reconstructed his notes in the book David Thompson's Narrative. Authors Rock Glover in 1971 and Victor Hopewood William Moreau.

David died in 1857, Quebec, Canada,

and buried in an unmarked grave until, in 1926, efforts by J.B. Tyrrell and the Canadian Historical Society placed a headstone on his grave in the Montreal Mt. Royal Cemetery.

This is a fascinating account of Thompson's life. I had heard the name before, but I had no idea that he had made such a great contribution to mapping in Canada and North America.

This is a very interesting account as I like to read about Explorers. I am reminded of two Indians Chain Singh and Nain Singh who explored Tibet in the 19 century and one can just imagine how difficult it would have been. I hadn't read about David Thompson and it was nice reading about him.
