Z badań nad biografiami członków warmińskiej kapituły katedralnej w pierwszym okresie jej funkcjonowania(do połowy XIV wieku)

The article presents the results of the research on the careers of twelve clergymen who became members of the Warmia cathedral chapter in the first century of its existence. The author discusses the careers of two bishops from Warmia [Ermland] – Eberhard von Neisse and Johann von Meissen along with the careers of other clergymen who also held important positions in the Church beyond the Warmia canonry (parish priests, canons of other chapters, workers in the chancery of grand masters). Thanks to a wide range of sources and studies along with the reanalysis and reinterpretation of the sources already known, we have managed to establish new facts and eliminate old inaccuracies which had for decades been present in historiography.
