While working on Physics as student and researcher in Dortmund, Wuppertal and Eindhoven, Kurt started to work with and on Linux, with first patches to the SCSI layer in the mid 90s. He has spent his post-university life in Open Source, as kernel engineer, leader of SUSE Labs (kernel, compiler, X11, security), and engineering and business leadership at SUSE. Since 2011 he has been working on Open Source cloud software, at Deutsche Telekom, as Freelancer, at T-Systems (as chief architect for the OTC) and also has been serving on the Open Infra Foundation's board. Since 2019 he has been pushing the Sovereign Cloud Stack idea which resulted in a publically funded project that he now technically leads. He still loves to occasionally write code (mostly python these days) or at least test out code from the colleagues and project. He spends his free time with his family or with running and playing table tennis.
