The Rothschild and Rockefeller families have teamed up to buy assets from banks and other distressed sellers in a union between two of the best-known names in financial history. RIT Capital Partners, which is chaired by Lord Rothschild, has taken a 37pc stake in Rockefeller Financial Services, the family's wealth advisory and asset management wing. It has snapped up the holding from French bank Socit Gnrale for less than 100m. The transatlantic alliance cements a five-decade acquaintance between the now ennobled Jacob Rothschild, 76, and David Rockefeller, 96, the grandson of the ruthlessly acquisitive American oilman and philanthropist John D Rockefeller. The two patricians now plan to capitalise on their family names to buy other asset managers or their portfolios, using their networks of top-notch contacts to ensure they get a seat at the table for any deal. The Rockefeller group goes back to 1882, set up to invest the family money made by John D Rockefeller's Standard Oil, the forerunner for today's Exxon Corporation, which he built with a Darwinian aggression.

The Rothschild banking dynasty has its roots in the 18th century when Mayer Amschel Rothschild set up a business in Frankfurt. That sprang to fame in 1815 when it bought government bonds in anticipation of Napoleon's defeat at Waterloo.
