Pierre Minier, or Le Minier, Minerii, was master of arts, in his fifth year in theological studies in 1403.

He is not to be confused with the Carmelite Pierre Meinier, bachelor of theology at Paris in 1432.
He must have died in 1432 or 1433. In 1432 we find an approval of the will of Pierre Minier, cure of Boos.

A very diligent witness at the Trial, upon the testimony of Houppeville, his opinion concerning Jeanne was not pleasing to Cauchon, who would not admit him to the editing of the Trial record.
His opinion was, however, included.
