William Cohan, the banker turned author, rose to prominence when he chronicled the history of his former employer Lazard in the best-selling The Last Tycoons. He followed this up with House of Cards, which recorded the fall of Bear Stearns. He speaks to Financial News about his latest book, Money and Power: How Goldman Sachs Came to Rule the World.

Money and Power goes back to the beginnings of Goldman Sachs's 142-year history and traces how the firm perfected an image of being the pre-eminent investment bank and documents its ability to survive financial and regulatory crises and its own internal power struggles.
