Klaus Knopper (* 1968 in Ingelheim) is the developer of the Linux distribution Knoppix and LINBO.
Knopper studied at the University of Kaiserslautern, where he completed his university degree as a graduate engineer in electrical engineering. During his studies, he supervised the German chess game GICS.
He works as a freelance IT consultant and developer in the open-source environment and also gives courses on various topics relating to free software. He is also a professor at Kaiserslautern University, Zweibrücken, where he is renowned for his lectures on IT.
In addition, Knopper has co-founded LinuxTag e. V., which is the bearer of the European Linux fair and conference of the same name. In 2005 Knopper left the club.
Encouraged by the experiences of his blind wife, Knopper developed the ADPLIANE  solution, which was named after her in Knoppix,  which makes it easier for blind people to use computers by translating them into spoken language.
Zudem hat Knopper den LinuxTag e. V. mitgegründet, welcher der Träger der gleichnamigen europäischen Linux-Messe und -Konferenz ist. 2005 verließ Knopper allerdings den Verein.
Angeregt durch die Erfahrungen seiner blinden Ehefrau entwickelte Knopper die nach ihr benannte in Knoppix integrierte Lösung ADRIANE, die es Blinden vereinfacht, Computer zu nutzen, indem sie ihnen den Bildschirminhalt in gesprochene Sprache übersetzt.
