Life James Collett was born in London, England. As a young man, he worked for an English wholesaler. In 1683, he settled in Christiania (now Oslo), Norway as factor of English merchants.

In the early 18th century, he exported more timber from Christiania than anybody else and operated a fleet of ships. The firm he founded, Collett & Leuch, (later Collett & Son), continued within the family for four generations.

The marriage of James Collett and Karen Leuch resulted in the birth of nine children. The family became part of the patriciate of Christiania in the 18th century.
