Jörg Schilling (Berlin, March 27, 1955 - October 10, 2021)  was a German engineer especially known for his work on software for recording compact discs,  whether data or audio, and as a supporter of the Solaris and OpenSolaris operating systems.   In his country he stood out as a popularizer of open source software, speaking for CCC, LinuxTag, among others.   [ 7] He was a board member and president of the Fraunhofer Institute for Open Communication Systems (FOKUS) in Berlin. 
He studied Electronic Engineering at the Technical University of Berlin, presenting his diploma thesis on optical media in UNIX systems in 1991.  At Fraunhofer FOKUS he carried out research tasks, where his main project was the website dedicated to open source BerliOS.   Schilling's work on CD recording software culminated after several years in the cdrtools package, which includes the popular cdrecord and the add-on programs mkisofs and cdda2wav. This package supports most CD burners and also works on most operating systems. In fact, it was the internally used program for most graphical interface CD burning software in the free software world, including the popular X-CD-Roast, K3b, and the Nautilus CD burning plugin.
Schilling was involved in a striking incident in early September 2006 when the Debian project responded to its license change  of the cdrtools package by forking CDRecord, creating a new development branch outside of its control, which is has named cdrkit. 
He was known for his frequent criticism of certain aspects of the Linux kernel  and for being one of the developers of the SchilliX distribution, the first OpenSolaris-based distribution 
Schilling was considered a controversial and uncompromising representative of the open source movement. German information technology expert Felix von Leitner called him a "titan among the heads of this world" and added: "Without heads there is no progress. We need more heads."  
Schilling conducted research at Fraunhofer FOKUS until his retirement in late 2020. He passed away on October 10, 2021 as a result of kidney cancer.
