From Eben Moglen's wikipedia page: Moglen is closely involved with the Free Software Foundation, serving as general counsel since 1994 and board member from 2000 to 2007. As counsel, Moglen was charged with enforcing the GNU General Public License (GPL) on behalf of the FSF,[4] and later became heavily involved with drafting version 3 of the GPL. I'm comfortable calling him the leading legal scholar of the GPL.
