Carnegie Investment Bank AB is a Swedish financial services group with activities in securities brokerage, investment banking and private banking. Founded in 1803, Carnegie is headquartered in Stockholm with offices across the Nordic region, as well as in London, New York, and Luxembourg. Carnegie was established as a trading company in 1803 when David Carnegie, Sr., a Scotsman, founded D. Carnegie & Co AB in Gothenburg. The management of the company was later succeeded by Carnegie's nephew, David Carnegie Jr., who later returned to Scotland, leaving the company, which by then had considerable interests in brewing and sugar production, in the hands of Oscar Ekman.
