From 1956 to 1968 - Director of the new Institute for Mechanical Research in Dresden. From 1968 until his retirement in 1986, he headed the Department of Mathematical Cybernetics and Computer Engineering at the Dresden Technical University.
He died in 1988 and was buried in the Striesener Friedhof cemetery.
- Scientific activity
While working at the Dresden Technical University, he was engaged in the development of computer technology, including the first desktop computer manufactured by the GDR. His most significant work is computers of models D1, D2 and D4a. The development of the D5 model was discontinued in 1966.
The computer server developed by Nikolaus Lehmann are in the German Museum in Munich .
