Jacob and Marcus Wallenberg'To move from the old to what is about to come, is the only tradition worth keeping.'

Marcus Wallenberg (1899-1982) 


This motto originates from a letter written by Marcus Wallenberg (1899-1982) to his brother Jacob Wallenberg (1892-1980), commenting on the sale of the family’s railroad business and new investments in aviation. This guiding principle still applies to how Investor works today.
