Ian Murdock (born 28 April 1973 in Konstanz, Germany) is a software engineer and hacker. He is the founder of the Debian GNU/Linux distribution and Progeny Linux Systems, a company providing services based on commercial distributions of operating systems built over the Linux kernel and distributed under a free software license such as the GNU General Public License (GPL).

He wrote the Debian Manifesto in 1993 while a student at Purdue University, where he earned his bachelor’s degree in computer science in 1996. He named Debian after his then-girlfriend Debra Lynn, and himself (Deb and Ian).[1] They subsequently married, filed for divorce in August 2007,[2] and were granted the divorce in January, 2008.[3]
