An extensive list of his ancestors is included in the Hamburgisches Geschlechterbuch.
At the age of 17 he was sent to Venice, where he learnt his trade as an apprentice in a Venice firm between 1735 and 1741. His father had started his career as an apprentice in the same firm.
He also held numerous honorary offices in Hamburg. In the same year senator Paul Berenberg died without heirs.
After Johann Berenberg"s death three years later, Johann Hinrich Gossler succeeded him as the company"s head and sole owner.
Hence Johann Berenberg"s daughter Elisabeth Berenberg remained as the only heir and last surviving member of the Berenberg family.
