1803
Carnegie was founded on 4 May 1803, when the Scotsman David Carnegie established the trading house D. Carnegie & Co AB in Gothenburg.

1836
David Carnegie Jr, the 23 year-old nephew of the founder, bought the Lorent sugar refinery and porter brewery at Klippan. They were Gothenburg's largest industries at the time.

1845
David Carnegie Jr returned to Scotland and employed Oscar Ekman to manage the business. When David Carnegie died in 1890, Oscar Ekman inherited a substantial number of shares in the companies.

1907
The responsibility for the business was taken over by Oscar Ekman's son-in-law, Karl Langenskiöld. The sugar operations were divested and became part of Svenska Sockerbolaget AB.

1932
In the wake of the Kreuger crash Karl Langenskiöld's son Carl Gustaf founded an investment bank, Bankirfirman Langenskiöld. At this time, the porter brewery was sold.

1980
The Langenskiöld investment bank changed name to Carnegie in 1980. Erik Penser had become its principal owner. In the late 1980's Carnegie expanded its businesses into Denmark southern Europe, London and New York.

1988
In 1988, Carnegie was sold to PKbanken (later Nordbanken).

1990
In the early 1990's Carnegie expanded into Finland, Norway and Luxembourg. Later, in the mid-1990s, Carnegie's Board of Directors made the strategic decision to narrow its geographic focus to the Nordic region, and between 1996 and 1997 Carnegie disposed of its southern European holdings. The strategy was to become the leading Nordic investment bank in securities broking, investment banking and asset management.

1994
In 1994, the newly formed company Carnegie Holding, with 55 per cent owned by the British merchant bank Singer & Friedlander and 45 per cent by Carnegie's personnel, acquired the operations from Nordbanken (now Nordea).

2001
Through a merger with Carnegie Holding, D. Carnegie & Co AB became the parent company of the Carnegie Group, and the Carnegie shares were listed on the O-list of the Stockholm Stock Exchange.
