Hans Reiser

Hans Thomas Reiser (born December 19, 1963) is an American computer programmer, entrepreneur, and convicted murderer. 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 Nina Reiser's body, which he revealed to be in a shallow grave near the couple's home. Prior to his incarceration, Reiser created the ReiserFS computer file system, which may be used by the Linux kernel but is now removed, as well as its attempted successor, Reiser4. In 2004, he founded Namesys, a corporation meant to coordinate the development of both file systems.
