Scott was born in early 1746 at the family home, Dunninald House in the parish of Craig, Angus to Robert Scott (1705–1780), the laird of Dunninald, and his wife, Ann.[2] He was educated at the University of St Andrews, before seeking his fortune in India. He built up a substantial merchant business in Bombay before moving to London in 1786 to direct the English end of his business. He became a director of the East India Company in 1788.[2]
In 1785 Scott helped James Charles Stuart Strange in a maritime fur trade. Strange commanded two ships that sailed from India to the Pacific Northwest Coast, collected sea otter furs, then sail to Guangzhou (Canton), China, to sell the furs for a large profit. Captain Cook's last voyage had demonstrated the potential for such a venture. Although the expedition was a commercial failure it explored and made discoveries in the Pacific Northwest, whose geography was only poorly understood at the time. In particular Strange and his captains explored the northern end of Vancouver Island, and discovered and named Queen Charlotte Sound and Queen Charlotte Strait.[3] They named the northwest extremity of Vancouver Island Cape Scott, in honor of David Scott.[4]
His son David Scott (1782–1851), who inherited Dunninald, had hoped to succeed his father as MP for Perth Burghs. However, by the time the younger Scott left his father's deathbed, Sir David Wedderburn had already secured so much support that even the backing of Lord Melville was unable to prevent defeat.[9]
