I met Minsky once in February 1987, at a rally in Las Vegas to protest the Nevada Test Site.. A lot of famous people (Carl Sagan, Barbara Boxer, Tom Downey, Ramsey Clark, Martin Sheen, Kris Kristofferson) were there, but I&#x27;d gone to meet Minsky.<p>I had taken along a (quite early) copy of the GNU Emacs manual. The FSF was selling them, but I&#x27;d put this one together myself. Running TeX on the texinfo source, converting the output for the Imagen printer, and then taking it to Kinko&#x27;s to be spiral bound, including my imitation of the yellow cover that the FSF version had.<p>I asked Minsky for his autograph. He looked at what I presented, understood what it was, an autographed inside the front cover, &quot;Marvin Minsky, friend of Stallman&quot;.<p>In April of 2011 in an airport in Honolulu, I presented that same manual for an autograph to Richard Stallman. He looked my manual over for a long time. IIRC, it documents Emacs version 16 or 17. Then he signed it, below Minsky&#x27;s autograph,
&quot;Richard M. Stallman - Friend of Minsky&quot;<p>RIP, Marvin.
