Similarly to all the earliest prelates in the newly baptized kingdom, he was a foreigner, most probably from Lombardy or France.
Most information on his life has been preserved in the Annales Posonienses and in a letter written by Bishop Fulbert of Chartres to him in the 1020s.
[1][2] Bonipert's correspondence with the Frankish prelate may reflect his French origin, but his name – which was quite frequently mentioned in charters issued in Lombardy around 1000 – suggests an Italian parentage.
[6] Bonipert was appointed to the see of Pécs in 1009[5] when the deed of foundation of the new diocese was issued in Győr in the presence of the papal legate, Azo.
[6] However, only the establishment of a cathedral school at Pécs is documented,[6] since Bonipert's request for a work by Priscian from Bishop Fulbert of Chartres must have been connected to it.
