Robert Morgenthau is 90 years old, a revered prosecutor fresh off a mammoth run as the Manhattan district attorney that ended when the calendar flipped to 2010. By almost any standard, he has had a complete legal career.

Except, remarkably, it is not over. An Associated Press story Wednesday morning reports that Morgenthau has accepted a position at Wachtell, Lipton, Rosen & Katz, a firm Morgenthau has apparently long admired, according to a statement he released Wednesday. Exactly what he is going to do at Wachtell and what his title will be are unclear at this moment. We’ve reached out to a spokeswoman at the firm, but we have yet to hear back.
