Bernard Gui, inquisitor (b. 1261 or 1262)

Bernard Gui (French: [ɡi]), also known as Bernardo Gui or Bernardus Guidonis (c. 1261/1262 – 30 December 1331), was a Dominican friar, Bishop of Lodève, and a papal inquisitor during the later stages of the Medieval Inquisition.

Due to his fictionalised portrayals in modern popular culture, most notably the 1980 Umberto Eco novel The Name of the Rose, he is "perhaps the most famous of all medieval inquisitors", although among his contemporaries and modern historians he is more often noted for his accomplishments in administration, diplomacy, and historical writing.
