This article was originally published on “2008-06-15 13:09:55 +0000”. I re-read it, and decided that it deserved to be re-published in Free Software Magazine as a tribute to those individual who made GNU/Linux possible. Every field has its own key individuals who donated much of their time to the ideas they believed in. Each one of them is a reminder that it’s up to individuals to make a difference — and to make history. Their work affects large chunks of the world’s population, and bring amazing changes to the way we see and experience the world.

The free software world has its own heroes. You probably know a lot of them already; if you don’t, you probably use the results of their work on a daily basis.

This article is both a tribute to them, and a summary to those people who are new to the free software world.
