Listening to this man has become a favorite time of mine of late. I'm saddened to hear he passed just as I was discovering his brilliant work. He was as far from a 'normal' person as you can get, but did great things, and had great insight.

As he was an inspiration for many of the stories that RadioLab did, they released the latest interview they did with him. I haven't listened to it yet, but knowing the two, it should be interesting.

And I would fathom they would be assembling a compilation of his interviews soon.
