This is the extraordinary story of Siegmund Warburg: the refugee from Nazi Germany who restored the Blitz-shattered City of London as the world's preeminent international financial centre. In recounting how this brilliant, scholarly man brought wit, passion and, above all, high ethical standards to the world of finance, Niall Ferguson shows how his meticulous methods were the antithesis of the debt-fuelled, speculative banking of our times.

'A fascinating portrait ... Beautifully paced, dramatically subtle and psychologically shrewd ... Warburg is an emblem of money as it ought to be, and now isn't' Bryan Appleyard, New Statesman

'Extensively researched and beautifully written' Peter Stormonth Darling, Spectator

'Ferguson's account of Warburg's life not only reveals a prophet of European unification and, later, globalization, but a banker from a more responsible (and civilised) era' Peter Mandelson, Daily Telegraph, Books of the Year

'A timely, original and engaging biography' Sathnam Sanghera, The Times

'Financially literate, extremely thorough, deploying dazzling breadth of cultural reference ... Ferguson has produced a fine historical biography. He has also reminded us, regrettably, that Warburg has no peer in the financial world today' Simon Shaw, Mail on Sunday
