Hank Paulson, appointed co-chairman and co-chief executive (to serve alongside Jon Corzine) of Goldman Sachs in June, is known for being intensely hard-working - although he says he has never prided himself on trying to work more hours a day than anyone else. A committed and active conservationist (along with his wife), he also likes to spend his holidays in the wild outdoors.
This summer, though, as he helps prepare the firm for the flotation expected in the autumn, he has had to limit himself to the odd long weekend fishing on the Florida Keys, while focusing more of his energy than ever before on banking.
His latest promotion - he was president and chief operating officer - does not, he says, change his job a great deal. "It's sort of a natural extension. We've had a history around here of shared leadership." But he admits that, while he is not one to worry, it is "an awesome responsibility".
Paulson is in favour of the flotation. "Listen, this is clearly the right thing for Goldman Sachs. The partnership is something we were all very attached to and it's not a decision we made easily."
