Richard Fuld is a character that even Wall Street, accustomed as it is to extravagance and mannerisms, has rarely seen: a climber without Ivy League sheen, a man who started at Lehman as an accountant in 1969, arrived at dawn and left late at night, fearless and ambitious enough to run 23 departments before he turned 40. An exceptional trader, those who know him tell me – someone who “could smell deals”, as Lehman banker Michael Petrucelli put it. But Fuld struggled with people and disliked talking; he preferred to move money. His face glowed green in the light of his screen as he barked out his infamous “rat-a-tat calls” – decisions made in seconds, involving millions and billions, fired off like rifle bursts.
