Free as in Freedom 

RichardStallman's Crusade for Free Software

By Sam Williams

------
A fairly balanced and interesting portrayal of the inventor of GnuEmacs, father of the FreeSoftwareFoundation and inventor of the GnuGeneralPublicLicense.

The book itself is released under the Gnu Free Documentation License and it might be an interesting experiment to port it over to a Wiki and watch it grow...
