'David Thompson' (
April 30,
1770 –
February 10,
1857), was an
English-Canadian fur trader, surveyor, and map-maker, known to some native peoples as "the Stargazer". Over his career he mapped over 3.9 million square kilometres of North America and for this has been described as the "greatest land geographer who ever lived."

Biography
Early life
Thompson was born in
London to recent
Welsh migrants David and Ann Thompson. When Thompson was two, his father died and the financial hardship of this occurrence resulted in his and his brother's placement in the
Grey Coat Hospital, a school for the disadvantaged of Westminster. He eventually graduated to the Grey Coat mathematical school and was introduced to basic navigation skills which would form the basis of his future career. In 1784, at the age of fourteen, he entered a seven-year apprenticeship with the
Hudson's Bay Company. He set sail on May 28th of that year, and left England forever.
[1]
The Hudson's Bay Company
He arrived in
Churchill (now in
Manitoba) and was put to work copying the personal papers of the governor of Fort Churchill,
Samuel Hearne. The next year he was transferred to nearby
York Factory, and over the next few years spent time as a clerk at Cumberland House and South Branch House before arriving at Manchester House in 1787. On
December 23,
1788, Thompson seriously fractured his leg, forcing him to spend the next two winters at Cumberland House convalescing. It was during this time he greatly refined and expanded his mathematical, astronomical and surveying skills under the tutelage of Hudson's Bay Company surveyor Philip Turnor.
In 1790 with his apprenticeship nearing its end, Thompson made the unusual request of a set of surveying tools in place of the typical parting gift of fine clothes offered by the company to those completing their indenture. He entered the employ of the Hudson's Bay Company as a fur trader and in 1792 completed his first significant survey, mapping a route to Lake Athabaska (presently straddling the Alberta/Saskatchewan border). In recognition of his map-making skills, the company promoted him to surveyor in 1794. Thompson continued working for the Hudson's Bay Company until
May 23,
1797 when he left and entered the employ of the competition, the
North West Company where he continued to work as a fur trader and surveyor.
North West Company
Thompson's decision to defect to the North West Company in 1797 without providing the customary one-year notice was not well received by his former employers. However, joining the North West Company allowed Thompson to pursue his interest in surveying and work on mapping the interior of what was to become Canada. In 1798, the company sent him to
Red Deer Lake (currently in
Alberta) to establish a trading post. Thompson spent the next few seasons trading based in Fort George (now in Alberta), and during this time led several expeditions into the
Rocky Mountains. In 1797, Thompson was sent south by his employers to survey of much of the Canada-U.S. boundary along the
49th parallel in the west, and from the St. Lawrence River to
Lake of the Woods to satisfy unresolved questions of territory arising from the
Jay Treaty between
Great Britain and the
United States. By 1798 Thompson had completed a survey of 6750 km (4,200 mi) from Grand Portage, through Lake Winnipeg, to the headwaters of the Assiniboine and Missouri Rivers, as well as two sides of Lake Superior.
[2]
In 1804, at the annual meeting of the North West Company in
Kaministiquia, Thompson was made a full partner of the company and spent the next few seasons based here managing the fur trading operations but still finding time to expand his surveys of the waterways around
Lake Superior. However, a decision was made at the 1806 company meeting to send Thompson back out into the interior. Concern over the
American-backed expedition of
Lewis and Clark prompted the North West Company to charge Thompson with the task of finding a route to the
Pacific in order to open up the lucrative trading territories of the Pacific North-West.
Columbia Travels
After the general meeting in 1806, Thompson travelled to
Rocky Mountain House and prepared for an expedition to follow the
Columbia River to the Pacific. In June 1807 Thompson crossed the Rocky Mountains and spend the summer surveying the Columbia basin. He helped establish
Kootenae House and later
Saleesh House thereby successfully extending North West Company fur trading territories. Over the next few seasons, Thompson continued to survey the area. Thompson mapped and established trading posts in Northwestern
Montana,
Idaho,
Washington, and Western Canada; including Saleesh House, the first trading post west of the Rockies in Montana. The maps he made of the Columbia River basin east of the
Cascade Mountains were of such high quality and detail that they continued to be regarded as authoritative well into the mid-20th century. in fact, Thompson’s drawings of the upper portion of the Missouri River were incorporated into a map for the Lewis and Clark expedition that followed seven years later. In early 1810, was Thompson returning eastward towards
Montreal but while on route at
Rainy Lake, received orders to return to the Rocky Mountains and establish a route to the mouth of the Columbia. This was a response by the North West Company to the plans of
John Jacob Astor to send a ship around the Americas to establish a fur trading post. During his return, Thompson was delayed by an angry group of
Peigan natives which ultimately forced him to seek a new route across the Rocky Mountains through the
Athabasca Pass. On
July 11,
1811, Thompson made it to the newly built
Fort Astoria, arriving two months after the
Pacific Fur Company's ship. Thompson wintered at Saleesh House before beginning his final journey back to Montreal in
1812.
In his published journals, Thompson recorded seeing large footprints near what is now
Jasper, Alberta, in
1811. It has been suggested that these prints were similar to what has since been called the
sasquatch. However, Thompson noted that these tracks showed "a small Nail at the end of each [toe]", and stated that these tracks "very much resembles a large Bear's Track".
[3]
Marriage and children
He married
Charlotte Small on
June 10 1799 at
ÃŽle-Ã -la-Crosse, a mixed-blood child of a Scottish fur trader and a
Cree mother. Their marriage was formalized at the Scotch Presbyterian Church in
Montreal on
October 30 1812. He and Charlotte had thirteen children together; five of them were born before he left the fur trade. The family did not adjust easily to life in Eastern Canada and two of the children, John (aged 5) and Emma (aged 7) died of round worms, a common parasite.
[1] Their marriage lasted 58 years, the longest Canadian pre-Confederation marriage known.

Later Years
Upon his arrival back in
Montreal, Thompson retired with a generous pension from the
North West Company. He settled in nearby
Terrebonne and worked on completing his great map, a summary of his lifetime of exploring and surveying the interior of North America. The map covered the wide area stetching from
Lake Superior to the
Pacific, and was given by Thompson to the North West Company. Thompson's
1814 map, his greatest achievement, was so accurate that 100 years later it was still the basis for many of the maps issued by the Canadian government. It now resides in the Archives of Ontario
[1].
In 1815, Thompson moved his family to
Williamstown, Upper Canada and a few year later was employed to survey the newly established borders with the
United States from
Lake of the Woods to the
Eastern Townships of
Quebec, established by
Treaty of Ghent after the
War of 1812. In 1843 Thompson completed his atlas of the region from
Hudson Bay to the Pacific Ocean.
Afterwards, Thompson returned to a life as a land owner, but soon financial misfortune would ruin him. By 1831 he was so deeply in debt he was forced to take up a position as a surveyor for the British American Land Company to provide for his family. His luck continued to worsen and he was forced to move in with this daughter and son-in-law in 1845. He began work on a manuscript chronicling his life exploring the continent, but this project was left unfinished when his sight failed him in 1851.
Death and afterward

1957 Stamp issued by
Canada Post to commemorate David Thompson's life
The land mass mapped by Thompson amounted to 3.9 million square kilometres of wilderness (one-fifth of the continent). His contemporary, the great explorer
Alexander Mackenzie, remarked that Thompson did more in ten months than he would have thought possible in two years.
Despite these significant achievements, Thompson died in Montreal in near obscurity on
February 10,
1857, his accomplishments almost unrecognized. He never finished the book of his 28 years in the fur trade, based on his 77 field notebooks, before he died. In the 1890s geologist
J.B. Tyrrell resurrected Thompson's notes and in 1916 published them as ''David Thompson's Narrative''.
[6]
Thompson's body was interred in Montreal's
Mount Royal Cemetery in an unmarked grave. It was not until 1926 that efforts by
J.B. Tyrell and the Canadian Historical Society resulted in the placing of a tombstone to mark his grave.
In
1957, one hundred years after his death, the Canadian government honoured him with his image on a
Canadian postage stamp. The
David Thompson Highway in
Alberta was named in his honour. His prowess as a geographer is now well-recognized. He has been called "the greatest land geographer who ever lived."
[[5] ]
There is a monument dedicated to David Thompson (maintained by the state of North Dakota) approximately two miles north and one mile west of Karlsruhe, ND.
The year 2007 marks the 150th year of Thompson's death and the 200th anniversary of his first crossing of the Rocky Mountains. Commemorative events and exhibits are planned across Canada and the United States from 2007 to 2011 as a celebration of his accomplishments.[2]
