Petrus Zwicker

Petrus Zwicker (died 1403) was an East Prussian Inquisitor and cleric of the Roman Catholic Order of the Celestines.

The victims of this persecution of heretics, in Austria, Pomerania, Brandenburg and Hungary, were almost exclusively Waldensians.

Petrus Zwicker came from Wormditt in East Prussia and worked in the North Bohemian town of Zittau till 1381 as school principal.

In the same year he entered the nearby Celestine monastery at Oybin.

As early as 1390 he was in charge of the persecution of heretics and from 1391 until his death in 1403 in Vienna presided over inquisitorial investigations that often took him on long journeys.
