Forgotten Names in Open Source - 2013 update

It is not the first time I write about forgotten names in Open Source world. However, I pretend to rewrite the list of forgotten names as time goes by, in order to include more names that I could have previously forgotten, or even that appear in the scene due to the increasing popularity in the actual Open Source scene.

For this reason, this post is not about Richard Stallman, Linus Torvalds, Miguel de Icaza, ... These are  recognized names in Open Source Software environment.

In the "Open Source Hall of Fame", the most known names would be, from my perspective:
- Linus Torvalds: Linux/Git
- Richard Stallman: GNU

Period. These two names are the most known names in the scene., and continue to be, up to date. With a little bit less importance, but still very known, there is a bunch of name including:

- Miguel de Icaza: Gnome/Mono
- Mattias Ettrich: Kde
- Bruce Perens: OSI/Debian
- Eric S. Raymond: OSI/fetchmail
- Donald E. Knuth: Latex
- Theo de Raadt: OpenBSD/OpenSSH
- Mark Shuttleworth: Ubuntu

Meanwhile, on the other hand, there is a much bigger bunch of names that are not as recognized as they should. The aim of this entry is to bring to foreground some of these names, in order to recognize their contribution to the Open Source Community, and also allow readers of this blog to make their opinions of other names that should be included.
