Is Martha Stewart the richest person to serve time in our federal prison system? How about any U.S. prison system?

I don’t know the answer, but it sure seems like a good question to ask.

Update: Leona Helmsley might have the lead at a current value of $2.2 Billion. She was worth much less at the time of her sentencing, because she inherited much of the wealth after her husband died after she was released. So, she may not be a winner. Martha is worth as of some time after her conviction about $335 million.
