Richard Stallman

Richard Matthew Stallman (born March 16, 1953) is an American software freedom activist, computer programmer, and founder of the free software movement. In 1983, Stallman announced the GNU project, an ambitious effort to create a free, Unix-compatible operating system, and in 1989 he wrote the GNU General Public License (GPL), which has become the most widely used free software license. Stallman's philosophy of software freedom—the idea that users should have the right to run, copy, distribute, study, and modify software—fundamentally challenged proprietary software models and has profoundly influenced the development of open-source software. His work led to the creation of essential tools that power much of modern computing infrastructure, including the GNU Compiler Collection and other foundational utilities. Beyond programming, Stallman has been a vocal advocate for digital rights and free culture, delivering lectures worldwide and engaging in activism around issues of software patents, digital rights management, and internet privacy. His ideological commitment to freedom in software has inspired generations of programmers and shaped the landscape of modern software development.
