Emacs Timeline
Emacs Timeline.

written: 8-Mar-1999
updated: 29-Oct-2007
Someone prodded me into drawing up a timeline of the Emacs family tree. Let me know if you have any additions/corrections.
This isn't intended to be a complete list of everything that has ever called itself Emacs -- as Craig Finseth's periodic posting of emacs implementations shows, that would be much larger than this.
However, I think this is fairly accurate for the GNU/Lucid/X Emacs part of the world, and their important predecessors.
(An explanation of how and why the FSF Emacs / Lucid Emacs split came about is over here.)
For more detail about the early days, please see Bernie Greenberg's paper, Multics Emacs: The History, Design and Implementation.
I've drawn lines only where code is shared, not merely ideas.
