Linus Torvalds year (1991). Version 1.0 was released on March 14, 1994. Torvalds first encountered the GNU Project in 1991, after another Swedish-speaking computer science student, Lars Wirzenius, took him to the University of Technology to listen to free software-guru Richard Stallman's speech. Torvalds used Stallman's GNU General Public License version 2 (GPLv2) for his Linux kernel. After a visit to Transmeta in late 1996, Torvalds accepted a position at the company in California, where he would work from February 1997 until June 2003. He then moved to the Open Source Development Labs, which has since merged with the Free Standards Group
