A biography of richard-stallman by technology journalist Sam Williams, first published in 2002. A revised second edition was released in 2010, with significant additions by Stallman himself. Brief entry — also documented in the Stallman KB.
What the Source Contributes
"Free as in Freedom" is the primary biographical source on Stallman and the formation of the free software movement through his lens. Williams conducted extensive interviews with Stallman and with figures who knew him from the MIT AI Lab era through the gnu-and-free-software-1983-1997 period.
The book is essential for understanding the hacker-culture-prehistory-1960s-1983 era — the MIT AI Lab culture of shared code and open collaboration that Stallman experienced before proprietary software displaced it. This context is necessary for understanding why gnu-manifesto-1983 reads as it does: it is not abstract idealism but a response to a specific loss.
Williams is both sympathetic and honest about Stallman's personality and the ways his uncompromising principles create friction. The biography documents how four-freedoms and copyleft emerged from specific experiences and disputes — not as abstract principles but as solutions to concrete problems.
The 2010 second edition is available under a free license at gnu.org. Stallman's additions and corrections to that edition are themselves primary source material — revealing what Stallman thought Williams got wrong or missed.
Used alongside revolution-os-2001 for the documentary record and rebel-code-moody-2001 for the broader Linux/movement history, this biography provides the deepest single-source account of the free software tradition's founding logic. The success-of-open-source-weber-2004 provides the complementary outside-view analysis.
