> had I been there 30 minutes early Sussman's wife, who proofread the book, would have signed it too!

I have thought that J Sussman not only proofread the book, but also came up with some of the problem sets and tested many of them: she worked through the book, not just a matter of spell-checking.

But I don't know.

In any event, SICP changed my world in a good way. Very cool that you got both authors to sign a copy!
