Richard Stallman

Richard Matthew Stallman is a software developer and software freedom activist. In 1983 he announced the project to develop the GNU operating system, a Unix-like operating system meant to be entirely free software, and has been the project’s leader ever since. With that announcement Stallman also launched the Free Software Movement. In October 1985 he started the Free Software Foundation.

The GNU/Linux system, which is a variant of GNU that also uses the kernel Linux developed by Linus Torvalds, are used in tens or hundreds of millions of computers, and are now preinstalled in computers available in retail stores. However, the distributors of these systems often disregard the ideas of freedom which make free software important.

That is why, since the mid-1990s, Stallman has spent most of his time in political advocacy for free software, and spreading the ethical ideas of the movement, as well as campaigning against both software patents and dangerous extension of copyright laws. Before that, Stallman developed a number of widely used software components of the GNU system, including the original Emacs, the GNU Compiler Collection, the GNU symbolic debugger (gdb), GNU Emacs, and various other programs for the GNU operating system.

Stallman pioneered the concept of copyleft, and is the main author of the GNU General Public License, the most widely used free software license.

Stallman gives speeches frequently about free software and related topics. Common speech titles include “The GNU Operating System and the Free Software movement”, “The Dangers of Software Patents”, and “Copyright and Community in the Age of the Computer Networks”. A fourth common topic consists of explaining the changes in version 3 of the GNU General Public License, which was released in June 2007.

In 1999, Stallman called for development of a free on-line encyclopedia through the means of inviting the public to contribute articles.

After personal meetings, Stallman has obtained positive statements about free software from the then-President of India, Dr. A.P.J. Abdul Kalam, from French 2007 presidential candidate Ségolène Royal, and from the president of Ecuador Rafael Correa. In Venezuela, Stallman has promoted the adoption of free software in the state’s oil company (PDVSA), in municipal government, and in the nation’s military.
