John Archibald Wheeler dead.

Phil Plait brings to my attention that John Archibald Wheeler died yesterday. As Phil says:

John Archibald Wheeler was a genius, an amazing physicist who felt that teaching as well as research was important. His students included Richard Feynman, widely recognized as one of the true geniuses of all time. His contributions to quantum mechanics and relativity were enormous. He invented the term black hole.

There is an obit over at Cosmic Variance and I’m sure more will follow.
