Surrealist Ball At Ferrières, 1972, Château De Ferrières, France

Nathan Mayer Rothschild initially started his business in Manchester in 1806, and gradually moved it to London, where in 1809 he acquired the location at 2 New Court in St. Swithin's Lane, City of London, where it operates today; he established N M Rothschild & Sons in 1811. In 1818, he arranged a £5 million (equal to £310 million in 2012) loan to the Prussian government, and the issuing of bonds for government loans formed a mainstay of his bank’s business. He gained a position of such power in the City of London that by 1825–6 he was able to supply enough coin to the Bank of England to enable it to avert a market liquidity crisis.
International high finance
In 1816, four of the brothers were each elevated to the hereditary nobility by Austrian Emperor Francis I; moreover, a fifth brother, Nathan, was elevated in 1818. All of them were granted the Austrian title of baron or Freiherr on 29 September 1822. As such, some members of the family used "de" or "von" Rothschild to acknowledge the grant of nobility. Barons (Knights) who received their title from the Holy Roman Emperor are known as Barons of the Holy Roman Empire, Reichsfreiherr, although the title is sometimes shortened to Freiherr.
