He studied
mechanical engineering, graduating in 1961, and afterwards receiving a
Doctorate in
electrical engineering in 1964 at the
University of Stuttgart, with thesis Zur Optimierung verfahrenstechnischer Regelkreise ("For the optimization of process control loops"). After finishing
habilitation in 1969 in Stuttgart, in 1971 he started working as an assistant professor, and in 1974 as an associate professor. Since 1975 he worked as a professor at the
University of Bochum in the Department of Automation and Process Automation. He retired in 2001.
He was the author of a widely used textbook on control engineering.
