Jochen Liedtke

Jochen Liedtke (born May 26, 1953 ; † June 10, 2001 ) was a German computer scientist who did significant work on microkernel architecture .

Life

Liedtke graduated from Bielefeld University in 1978 with a degree in mathematics. His diploma thesis dealt with a translator for the programming language ELAN, which was then used in school lessons . During subsequent work on an ELAN environment for the Z80 , he was able to build on it and created a runtime environment, which resulted in Liedtke's first, complete micro -kernel system with the L2 ("EUMEL") designed for an 8-bit computer (L1 was already one of his interpreter designed as a student for a subset of Algol 60 ).

From 1984 Liedtke worked at GMD , where he was able to improve L2 in the following years and port it to 16-bit computers, thus creating the L3 system, the predecessor of the well-known L4 system developed by him and others from the mid-1990s. Family . Jochen Liedtke received his doctorate in 1996 at the Technical University of Berlin with a thesis on guarded page tables and only a little later switched to the Thomas J. Watson Research Center ( IBM ), where he mainly dealt with the unification of microkernel ideas and Linux . Since 1999 he was professor for system architecture at the University of Karlsruhe .
