Who is Hans Reiser?

Hans Thomas Reiser is an American computer programmer, entrepreneur, and convicted murderer. He is the creator and primary developer of the ReiserFS computer file system, which is contained within the Linux kernel, as well as its attempted successor, Reiser4. In 2004, he founded Namesys, a corporation meant to coordinate the development of both file systems. In April 2008, Reiser was convicted of the first degree murder of his wife, Nina Reiser, who disappeared in September 2006. He subsequently pleaded guilty to a reduced charge of second-degree murder, as part of a settlement agreement that included disclosing the location of his wife's body, revealed to be in a shallow grave near the couple's home.
