Jean de Bouesgue, or Le Boesgue, or Bouège, was a Benedictine, bachelor and licentiate in 1403, master of theology and prior of the cloister and almoner of the abbey of the Holy Trinity at Fécamp from 1406.

He was very much in favor with the University, which sent him as ambassador to Jean XXIII in order to obtain the revocation of the Bull of Alexander V in favor of the Mendicants in 1411- Jean de Bouesgue was attacked by brigands on the outskirts of Rome. He preached before the Pope and Cardinals.

He became a friend of the Pope, who granted him in 1412 the priory of Gournay, and he is described as honorary chaplain of the Pontiff in 1416. But we know that in 1408 he was prosecuted before the church court of Paris by Estoud d'Estouteville for the maladministration of his abbey and negligence in caring for the poor and the lepers.

On March 18, 1422, we see Jean de Bouesgue entrusted by his colleagues with treating with the Bishop of Chester, Chancellor of Normandy, in the matter of the property of the abbey of Fécamp in England. He was designated by the University of Paris to go to the King of England and the Duke of Burgundy to obtain confirmation of its privileges. He was enjoined, beforehand, to communicate the instructions he had received to Pierre Cauchon.

In 1423 Jean de Bouesgue is referred to as master regent of theology at Paris, a charge that he gave up the following year. He was imprisoned over a dispute he had with the English council over a trial of clerics of Fécamp, but the University intervened on his behalf with the Duke of Bedford and the Abbot of Fécamp. We find him again master regent at Paris in 1433.

It is not astonishing to see a doctor of theology of Paris for twenty-five years, and an almoner of the abbey of Fécamp judging as did his teachers and his lord abbot. He agreed energetically.
