Olof Söderberg, together with Joseph Nachmanson and Knut Wallenberg, were the initiators behind the Stockholm School of Economics Association in 1906. Per Johan Söderberg was also a founding board member of the association. The Stockholm School of Economics opened three years later. The mission of the school was ”to promote the advancement of business operations within the country through scientific teaching and research”. Olof Söderberg had himself demonstrated a talent for studies, but was advised against engaging in commerce since that was not considered an appropriate area for a learned man. Against that background, it is easy to understand his involvement in the creation of an advanced education, including one for future businessmen. In 1927, Söderberg became a board member of the Stockholm School of Economics and its treasurer.
