From Wikipedia, the "open source encyclopedia", again all very straightforward, except for those seemingly attempting to cover it all up:
http://en.wikipedia.org/wiki/Richard_Stallman
Richard Matthew Stallman (frequently abbreviated to RMS) (born March 16, 1953) is the founder of the free software movement, the GNU project, and the Free Software Foundation. An acclaimed programmer, his major accomplishments include Emacs (and the later GNU Emacs), the GNU C Compiler, and the GNU Debugger. He is also the author of the GNU General Public License (GNU GPL or GPL), the most widely-used free software license, which pioneered the concept of the copyleft.
Instead of reading from a third party, why don't you go to gnu.org and read Stallman's own history of how it all started. That fits with what I told you.
