  In June 1971, R ichard  M atthew  S tallman joined MIT Artificial Intelligence Laboratory as a programmer where he gained popularity with the hacker community and came to be known by his now popular name  RMS . At that time, all the programmers used to share their code freely among each other cutting across various institutions

  In 1980, withthe advent of portable software - ie software that can be compiled to run on different computers, a business model emerged. So the companies developing the code refused to share the code with their clients and began restricting copying and redistribution of their software by copyrighting it.

  In response tothis trend, Stallman, who believed in the principle that software has to be free always, founded the Free Software Foundation and in 1985, published the GNU Manifesto. This manifesto outlined his motivation for creating a free OS called GNU, which would be compatible with Unix. He along with a group of like minded programmers started work in developing the tools needed to make a complete OS

  In 1990, Afinnish student by name Linus Torvalds studying in the University of Helsinki came into contact with Andy Tanenbaum's OS, Minix. Linus wanted to upgrade Minix by putting in more features and improvements. But he was prohibited by Tanenbaum to do so. Then Linus decided to write his own kernel and released it under GPL. This kernel is now popularly known as Linux

  Once Linus wentto the southern hemisphere on a vacation There he encountered a penguin As he tried to pat it, the penguin bit his hand.  This amusing incident led to the selection of a penguin as the logo of Linux sometime later.
