Whose creation is Linux?

Torvalds posted in an online newsgroup that he was building a free operating system, adding that it was “just a hobby, won’t be big and professional”. The first version, 0.01, was released in September 1991, and in 1992 he placed it under the GNU General Public License, allowing anyone to use and change the code. Thousands of developers around the world have since contributed to it. Linux now powers most of the internet’s servers, the Android operating system and every one of the world’s 500 fastest supercomputers. Torvalds also created Git, the version control system, in 2005.
