I never met Marty Zivin, but I corresponded with him many times over the past thirty years. He was a radio guy, inside and out. It's been pretty obvious to his facebook friends (I was one of them) that this day was approaching. Marty posted as often as he could, and didn't hold back with statements of despair and grief. It's a real bummer that he's gone.
Robert Feder has the details.
