Z:gnu-www-ja-rms-lisp--89334c-During the 1970s, before my li/en

During the 1970s, before my life became politicized by horrible events, I was just going along making one extension after another for various programs, and most of them did not have anything to do with Lisp. But, along the way, I wrote a text editor, Emacs. The interesting idea about Emacs was that it had a programming language, and the user's editing commands would be written in that interpreted programming language, so that you could load new commands into your editor while you were editing. You could edit the programs you were using and then go on editing with them. So, we had a system that was useful for things other than programming, and yet you could program it while you were using it. I don't know if it was the first one of those, but it certainly was the first editor like that.
