Richard Stallman

**Richard Stallman** launched the free software movement in 1983 and started the development of the GNU operating system (www.gnu.org) in 1984. (GNU is free software: everyone has the freedom to copy it and redistribute it, with or without changes. The GNU/Linux system, basically the GNU operating system with Linux added, is used on tens of millions of computers today.) He has received the ACM Grace Hopper Award, a MacArthur Foundation fellowship, the Electronic Frontier Foundation’s Pioneer Award, and the Takeda Award for Social/Economic Betterment, as well as several doctorates honoris causa, and has been inducted into the Internet Hall of Fame.
