Richard Stallman (born 1953)
Born 1953 CE.
Richard Matthew Stallman ( STAWL-mən; born March 16, 1953), also known by his initials rms, is an American free software movement activist and programmer. He campaigns for software to be distributed in such a manner that its users have the freedom to use, study, distribute, and modify that software. Software which ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation (FSF) in October 1985, developed the GNU C Compiler and GNU Emacs, and wrote all versions of the GNU General Public License. Stallman launched the GNU Project in September 1983 to write a Unix-like computer operating system composed entirely of free software. With that he also launched the free software movement. He has been GNU Project's lead architect and organizer, and developed a number of pieces of widely used GNU software including among others, the GNU C Compiler (GCC) version 1.0 (that later was expanded and renamed GNU Compiler Collection), GNU Debugger, and GNU Emacs text editor. Stallman pioneered the concept of copyleft, which uses the principles of copyright law to preserve the right to use, modify, and distribute free software.
