Being raised in a textile trading family in a village in the upper Alsace region and having spent his apprenticeship years as a trading assistant between the British and French trading empire, as well as a supplier of the French and allied armies, Isaac Dreyfus-Bernheim settles down in Basel and establishes himself as an middleman and shipper of textiles.


Registration of the textiles trading house "Isaac Dreyfus" in the commercial register of Basel.
As the trade in goods goes naturally hand in hand with credit and guarantee services issued in the form of bills of exchange, the management of bills of exchange and the issuing of cash loans evolved into an own line of business.
