Likewise, especially given my recent interest in Lisp. I actually own a paper copy of the LISP 1.5 Programmer's Manual, thanks to Baltimore's excellent free book exchange [1]; I haven't cracked it yet in any serious way, but this news might push it up my stack a bit, especially since I also now know it's possible to emulate an IBM 7094 on which to actually run Lisp 1.5. (I've also thought about implementing a Lisp 1.5 interpreter on Common Lisp, but I'm afraid that's going to have to wait until I have a bit more clue about both of those languages and about the differences between them.)
Working on it. Really solid sources are a bit sparse, though. It's one of those odd cases, which I think are both problematic but interesting for Wikipedia: someone who is clearly notable, but proper bios on him don't really exist, just scattered mentions that need to be tied together. It's a lot easier to write bios on people who already have other bios written on them (since that solves the problem of what to cite pretty easily).
