Bernhard Baron von Eskeles was also a founding member of the Erste oesterreichische Spar-Casse. He was born in Vienna on 12 January 1753, the son of a rabbi. Bernhard Eskeles the Elder died in the same year. The son moved to Amsterdam with his mother Hanna Wertheimer at the age of 17, where he got a job and commercial training in a trading business. He was already running his own business by 1770 but returned to Vienna in 1773. He became a partner in the trading house of Nathan Adam Arnsteiner and his brother-in-law Salomon Hertz, the wholesale and banking house which soon operated solely under the name Arnsteiner & Eskeles. Its business encompassed the insurance of state bonds, the financing of infrastructure such as the rail connection between Milan and Venice, financial transactions, moneylending, and military contracting. Through these activities, the bank came to occupy a central position within the state apparatus of that period. Eskeles made a name for himself as a consultant to the Emperors Joseph II and Francis II. In April 1815, he signed a petition to Emperor Francis I to grant Jews in Austria legal equality: the petition was denied. In the following year, 1816, Eskeles co-founded the Austrian National Bank and became its first director and vice governor. Three years later, he and Johann Baptist Weber were among the founders of the Erste österreichische Spar-Casse.
Bernhard Eskeles’ private wealth was significantly increased through his marriage to Cäcilie Itzig from Berlin, a sister-in-law of his partner Arnsteiner. He used it to grant large loans to the Austrian state during the Napoleonic Wars. For this reason, Eskeles, who had already been granted nobility in 1797, was made a knight in 1811 and a baron in 1822. Eskeles contributed significantly to the organisation of the European money market, as well as launching several charitable foundations. In 1820 he acquired the Palais at Dorotheergasse 11, had it thoroughly renovated and, with his wife Cäcilie, made the salon a meeting point for representatives from art and science. During the Congress of Vienna in 1814/15, Talleyrand, Hardenberg and Wellington were among the guests who also were frequent visitors at the city’s most famous salon, hosted by Cäcilie’s sister Fanny von Arnstein. Today, Vienna’s Jewish Museum is housed in the Palais Eskeles.
