For those of you interested in the history of Emacs, how it all started, and where it got its name, here is an original document from 1979 written by Richard Stallman that describers the new Emacs system.
I found the paper in this this post that references an update to the original paper. EricIO added a pointer to the orginal paper that I’ve linked above. There’s a lot of good information in the comments including a Twitter thread that discusses how Stallman eventually settled on the name Emacs.
For the day-to-day programmer, none of this matters a bit but for those of us who care about our backstory and how we got here, it’s a nice addition to the narrative. The whole thing—other than the actual paper—is short so take a look if you’re interested in our history.
