Bernhard (Berush) Baron von Eskeles (1753–1839) was born in Vienna as the son of a rabbi. In 1773, he founded the Arnstein und Eskeles banking house with his brother-in-law Nathan Arnstein. Later he served as an advisor to emperors Joseph II and Franz II, and was made a knight and baron for his generous funding. In 1816, he co-founded the Austrian National Bank and was involved in the founding of the Österreichische Spar-Casse. Eskeles was married to Cäcilie, née Itzig, the sister of Fanny von Arnstein.
From 1823 to 1827, the Palais at Dorotheergasse 11 was owned by the Arnstein und Eskeles bank. Bernhard von Eskeles was buried in the Jewish cemetery in Währing.
