De Mouchy was born at
Ressons-sur-Matz, near
Beauvais, in
Picardy. In 1539 he was appointed rector of the
University of Paris. He was also professor at the Sorbonne and
canon Penitentiarius of
Noyon. He was one of a group of Sorbonne doctors who in the 1550s began detailed scholarship on lists of bishops, to support the
apostolic succession. As
inquisitor fidei he exerted his influence against the
Calvinists, and was a judge at the heresy trial of
Anne du Bourg. In a 1560 book he accused Calvinists of sexual libertinism, practiced after the end of religious services. In 1562 he accompanied
Charles, Cardinal of Lorraine to the
Council of Trent, and in 1564 was present at the
Synod of Reims. ==Works==
