After the end of the Second World War Cornelius Freiherr v. Berenberg-Gossler and his son Heinrich, who had already joined the business as partner in 1935, decided to begin active banking with the now more than 350-yearold company once more. In the course of this the Hamburg branch of the North German Credit Bank, Bremen, was taken over, as the Bremer had to divest it to comply with the bi-zone law. In return the North German Credit Bank received a shareholding. On 21 June 1948, the day after the currency reform, the old company reopened for business in its new home on the Alter Wall.

In the stormy reconstruction years Joh. Berenberg, Gossler & Co. was active in many fields. Industrial regeneration and the start of export trade brought a large number of the old customers back and it was possible to take up quickly the foreign connections of earlier years. Cornelius Freiherr v. Berenberg-Gossler died in 1953.

The management of the business was now in the hands of Heinrich Freiherr v. Berenberg-Gossler and August Rohdewald, until the latter left in 1961 to take up a position on the board of the Reconstruction Loan Corporation in Frankfurt am Main. The successful development of the business made an enlargement of the partnership desirable.

In 1961 Heinz A. Lessing and in 1967 Joachim H. Wetzel joined the business as partners with unlimited liability. The North German Credit Bank opted out of its shareholding in 1974. A 25% share has been held since then by the North German State Bank, Hanover and was purchased in 2010 from the PetRie Beteiligungsgesellschaft and Berenberg Family .
