The evasive mastermind behind the finance-culture thorn Twitter @GSElevator was revealed today to be neither former or current employee of Goldman Sachs. The account, which has over 600,000 followers and a six-figure book deal, is maintained by a bond executive in Texas. Twist.

In a conversation with Dealbook, @GSElevator (née John Lefevre) admitted to keeping up with the account as "a joke to entertain myself."

But the big reveal comes with good news for all Goldman employees:

A Goldman spokesman, after being told that @GSElevator had been unmasked, said in a statement, "We are pleased to report that the official ban on talking in elevators will be lifted effective immediately."
