The story
It was founded in February 1912 by Knut Agathon Wallenberg of the Stockholms Enskilda Bank and Emil Glückstadt of Landmandsbanken (Copenhagen), together with several other banks including Centralbanken for Norge (Christiania), Azov-Don Commercial Bank (Petrograd), and Banque de Paris et des Pays-Bas (Paris). The purpose of the bank was to facilitate trade between the United Kingdom and northern Europe.
In June 1919 the bank offered the chairmanship of its board to John Maynard Keynes with the assurance that in return for a salary of £2000 the job would only take a morning a week. Keynes had met Wallenberg and Glückstadt during World War I and the offer was attractive. However, Keynes consulted with several bankers in the City and turned the offer down.
In October 1920 British Bank of Northern Commerce merged with C.J. Hambro & Sons, with the combined bank taking the name Hambros Bank of Northern Commerce. In August 1921 the bank shortened its name to Hambros Bank, in part because it did not want a name that was too limiting.
