I have to admit, I don't know the work of most of them, which is something I plan to remedy ASAP. However, there are plenty in there whom I do know: Brian Kernighan, Tim Bray, Elliotte Rusty Harold, Charles Petzold, Simon Peyton Jones and last, but definitely not least, Yukihiro Matsumoto!
The titles of the other essays have me intrigued enough to search out details of their authors, too.
Sadly, the book isn't due out until sometime in June, when all my time will be consumed reading iPhone reviews :-).
