Lajos Mitterpacher (1734−1834) natural scientist, professor of technology, natural history and agronomy, and Mátyás Piller (1733–1788) Styrian-born professor of natural history were Jesuit co-orders and later fellow teachers at the Royal Hungarian University. Their joint work, Iter per Poseganam Sclavoniae provinciam mensibus Junio, et Julio anno MDCCLXXXI susceptum (“Journey to the Slavonian Pozsega county in June and July of 1782”), was published in Buda. In addition to their historical, ethnographical, geographical, zoological and botanical observations, they published the description of several new plant species in their book.
