That's an oversimplification.  RMS may have done most of the work, but
he was not the first.  Here's some interesting reading from 1978:

That's right.

RMS is often credited with the ^R real-time display feature, but that
too originated earlier by Mikkelsen.

Also correct.  I found a copy of GNU Emacs 13.8 which I believe is the
first version to be distributed.  It has the Gosling display code.
