History

Investor AB was established in Stockholm when new Swedish legislation made it more difficult for banks to own stocks in industrial companies on a long-term basis. The shareholdings of the Wallenberg family bank, Stockholms Enskilda Bank, were transferred to Investor AB, a newly formed industrial holding company spun off from the bank, which would serve as the family's investment arm henceforth.
