In 1982, he founded the Free Software Foundation (FSF) and dedicated himself to producing high-quality, free software. He began the programming and implementation of a full clone of UNIX, written in C and available to the hacker community for free. He succeeded—with the help of a large and active programmer community—to develop most of the software environment of a typical UNIX system, but he had to wait for the Linux movement to gain momentum before a UNIX-like operating system kernel became as freely available as he (and like-minded others) had continuously demanded. In 2002, a book written by Sam Williams entitled Free as in Freedom: Richard Stallman’s Crusade for Free Software, chronicles Stallman’s life, discusses his motivations for wanting free software, and gives insights into his highly creative hacker personality. Stallman’s personal home page can be found at http://www.stallman.org/.
