At 14, David Thompson apprenticed (and indentured) himself to the Hudson's Bay company and in 1784, sailed for Canada. At the end of his indenture he requested, and was granted, a set of surveying tools and set off to become the most prolific land geographer in history. Thompson explored and surveyed more than 3 million square kilometers of North America. http://en.wikipedia.org/wiki/David_Thompson_ (explorer) http://www.thefurtrapper.com/david_thompson.htm
