Alan Cox (born 22 July 1968) is a British computer programmer who has been a key figure in the development of Linux. He maintained the 2.2 branch of the Linux kernel and continues to be heavily involved in the development of the Linux kernel, an association that dates back to 1991. He lives in Swansea, Wales, where he lived with his wife Telsa Gwynne, who died in 2015 and now lives with author Tara Neale, who he married in 2020. He graduated with a BSc in Computer Science from Swansea University in 1991 and received an MBA from the same university in 2005.
Involvement in the Linux kernel
While employed on the campus of Swansea University, Cox installed a very early version of Linux on one of the machines belonging to the university computer society.  This was one of the first Linux installations on a busy network and revealed many bugs in the networking code. Cox fixed many of these bugs and went on to rewrite much of the networking subsystem. He then became one of the main developers and maintainers of the whole kernel.
He maintained the 2.2 branch, and his own versions of the 2.4 branch (signified by an "ac" in the version, for example 2.4.13-ac1). This branch was very stable and contained bugfixes that went directly into the vendor kernels.
Alan was employed by the Linux distributor Red Hat during 1999–2009. Starting from 2011 he was employed by Intel Corporation but left both Intel and Linux kernel development in January 2013 to care full-time for his wife during a critical period of medical treatment, and returned to both later that year, until taking early retirement at the end of 2019.
Fuzix: because small is beautiful
On 31 Oct 2014, Alan Cox announced Fuzix OS, a tiny system V kernel, initially for Z80 on Google+:
Fed up of SystemD?
Kdbus the final straw?
Linux community too large and noisy?
Yearn for the good old days when you knew every contributor by name and the source code fitted on a single floppy disc?
Cox is an ardent supporter of programming freedom, and an outspoken opponent of software patents, the DMCA and the CBDTPA. He resigned from a subgroup of Usenix in protest, and said he would not visit the United States for fear of being imprisoned after the arrest of Dmitry Sklyarov for DMCA violations.
In January 2007, he applied for a series of patents on "RMS", or "rights management systems". Red Hat Inc., Cox's former employer, has stated (in a document drafted by Mark Webbink and Cox himself) that it will not use patents against free software projects.
He received an honorary doctorate from the Swansea University, his alma mater, on 20 July 2016.
