Berenberg Bank
Joh.
 Berenberg, Gossler & Co.
 KG, commonly known as Berenberg Bank, is a Hamburg-based multinational investment banking and private banking company, founded by the Belgian-origined Berenberg family in 1590.

 Its owners, the Berenberg/Gossler family, belonged to the ruling elite of Hanseatic merchants of the city-republic of Hamburg and several family members served in the city-state's government from 1735.
 Like many other merchant bankers, the Berenbergs were originally cloth merchants.
 The bank's name refers to Johann Berenberg and his son-in-law Johann Hinrich Gossler, and has remained unchanged since 1791.
Berenberg family
The Berenberg family (Dutch for "bear mountain") was a Flemish-origined Hanseatic family of merchants, bankers and senators in Hamburg, with branches in London, Livorno and other European cities.
 The family was descended from the brothers Hans and Paul Berenberg from Antwerp, who came as Protestant refugees to the city-republic of Hamburg following the Fall of Antwerp in 1585 and who established what is now Berenberg Bank in Hamburg in 1590.
 The Berenbergs were originally cloth merchants and became involved in merchant banking in the 16th century.
 Having existed continuously since 1590, Berenberg Bank is the world's oldest surviving merchant bank.
