Robert Jolivet of Montpichon, Joliveti R. abbas Montis, R. abbé da Mont, was a Norman Benedictine, a bachelor of law in 1416, and became Abbot of Mont Saint Michel in 1411.

He fled from his abbey which remained faithful to Charles VII and took refuge with the English about 141g.
He went on various missions for Bedford, and became his chancellor and keeper of his privy seal in 1423.
We see Robert Jolivet on May 27, 1428, as the representative of Bedford at the foundation of the Carmelites in Rouen.

Extremely devoted to the government of Henry VI, this religious played an important role in diplomacy and even in military matters, inspecting troops and visiting fortresses. He was a member of all the important councils. In 1425 he was commissioned by the King of England to recover the abbey which he had so admirably fortified before his departure.

Between April and June, 1428, Robert Jolivet was at Paris awaiting the coming of Salisbury and the English army "to advise and conclude where he would be sent." In November he went to Mantes to see Bedford about the siege of Orleans. On September 12, 1430, Jolivet is cited as chancellor with the considerable salary of 800 livres a year. He resided at Rouen in order to serve the King.

On November 16, 1431, King Henry ordered the payment of the wages of the ten lancers and thirty mounted archers who had escorted him (with the Abbot of Fécamp) to Paris where he had been summoned. On July 23, 1436, King Henry VI ordered him and the Bishop of Lisieux and the Earl of Suffolk to call together the Three Estates at Caen and to take part in the project of establishing a university there.

Jolivet was buried at Rouen in the church of Saint Michel in July, 1444.
