Richard Fuld Jr., Chairman and CEO of Lehman Brothers, USA, speaks at the World Economic Forum in New York in this February 1, 2002 file photo. Not long ago, when Lehman Brothers CEO Fuld talked about "everyone's worst nightmare" he was referring to a massive fraud at French bank Societe Generale. Just a few months later Fuld, a 30-year-veteran of Lehman who had ably steered it through near-death experiences like the Asian debt crisis of 1998, is living his own worst nightmare as the venerable investment bank stands on the verge of collapse.
