Georg Robert von Pasterwitz (7 June 1730 – 26 January 1803) was an Austrian composer and teacher.
It was during this time that he met Johann Ernst Eberlin, who became his music teacher.
Pasterwitz completed his studies in 1759 and soon started teaching philosophy at the monastery's Ritterakademie, eventually rising to teach courses in mathematics, physics, economics, and political science; since about 1755 he was also active as composer, producing stage works for the monastery almost every year.
Due to reforms started by Joseph II, he had to give up some of his duties and became instead the monastery's treasurer and eventually official representative, when it was threatened with dissolution in 1785.
For the monastery, Pasterwitz regularly composed dramas and dozens of liturgical pieces: masses, offertories, vespers, etc.
