Timothy Hart, Rest in Peace

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).

Old age, from the sound of it:

> Timothy Paul Hart of Cambridge, formerly of Lexington, died peacefully in his sleep on January 20, 2014 at the age of 74, surrounded by members of his family.
