法學博士
In Jena he followed the customs of the time and to first studied the philosophical sciences, and then turned to a degree in law. On 9 September 1593 he continued his studies at the University of Wittenberg. He completed his doctorate there on 7 March 1598 with a degree of Doctor of law. As early as 1595, Hirschbach acted as a tutor and teacher for a number of young nobles, in Wittenberg and also in Leipzig. Apparently, his lessons had merit and on 30 September the Electoral family 1601 hired him as preceptor of Duke August of Saxony. After his brother in law Benedikt Carpzov the elder left Wittenberg in 1602, Hirschbach was appointed professor on the fourth chair, presumably on the recommendation of the Electoral family.
