1. Jonathan Nadeau
Jonathan Nadeau is the creator of Sonar Linux, a customized Ubuntu-based distro designed with an emphasis on accessibility features for disabled users. He’s also an activist working for more accessible computing, and an outspoken free software proponent who is the driving force behind the Northeast GNU/Linux Fest.
Nadeau, 35, has been blind since 1992, having lost his sight in a car accident at the age of 14. His work on behalf of disabled users first gained attention in 2011, when, as an intern at the Free Software Foundation, he pushed for the inclusion of numerous accessibility features in version 5.0 of Trisquel, the all-free-software fork of Ubuntu.
