Richard Stallman

Dr. Richard Stallman launched the free software movement in 1983 and started the development of the GNU operating system 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.

Stallman has received the ACM Grace Hopper Award and the ACM Software and Systems 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.
