J.R. Mühlbacher "finished" his education by a PhD in Mathematics (Algorithmic Graph Theory) at the University of Vienna in 1969. However, during his studies he worked as a software engineer, called "Programmer" in these days. Then he was employed at JKU, Austria (Habilitation 1973). In that time CS did not exist as an acknowledged science yet. In 1973 he was elected as Professor (C3) at University of Dortmund, Germany, and in 1976 he moved back to JKU as Full Professor. He was visiting professor at the University of Zürich and St. Gallen (Switzerland), Reading (UK), Granada (Spain) - teaching on Data Structures, Operating Systems, Networks.
