UK: Outsider who changed the City.

Forced to flee from Nazi Germany, Siegmund Warburg landed in London, where he set up the influential bank, SG Warburg, and, as Rhymer Rigby reports, left an indelible print.

Sir Siegmund Warburg was a remarkable man from the most remarkable generation of a remarkable family.
