Erin Callan has officially left Credit Suisse. It is not known whether Callan, once dubbed the most powerful woman on Wall Street, left the bank in a limo.

Callan was the short-lived chief financial officer at Lehman Brothers who once hung a framed photograph in her office of herself getting out of a limo. The picture came from a Portfolio magazine article which called her "The most powerful woman on Wall Street", according to Andrew Ross Sorkin's book, 'Too Big To Fail.'
