A Premonstratensian (1772), he was a professor at Olmütz (1774), then (1789) professor of Oriental studies, introduction to the Old Testament and archaeology at Vienna, where in 1803 the chair of dogma was also entrusted to him. Although a man of wide and choice erudition, J. had to be removed from his chair because of his excessively free opinions, tending toward rationalism.
