Krengel grew up in Hann after the war . Open up. He then studied mathematics, physics and chemistry for teaching at the Georg-August University in Göttingen and the Ludwig Maximilians University in Munich . In 1963 he received his doctorate in Göttingen under Konrad Jacobs with the thesis On the Absolute Amount of Continuous Linear Operators and its Application to Ergodic Decompositions . In 1964, Krengel went to the Statistics Department at the University of California at Berkeley as a Visiting Assistant Professor . He then followed his teacher Konrad Jacobs to the University of Erlangen-Nuremberg , where he also completed his habilitation in 1967. After only a brief intermezzo as a private lecturer in Erlangen, he was appointed full professor at Ohio State University in Columbus in 1968 . In 1971 he finally returned to Göttingen as the successor of Jacobs and built up the Institute for Mathematical Stochastics there. In 2002 he retired. Since 1993 he has been a full member of the Academy of Sciences in Göttingen .
