Richard de Grouchet, master of arts, is referred to in a register of the University in 1403.

He taught grammar at Rouen. Bachelor of theology, he preached in the cathedral in 1439 and obtained by favor of the Chapter one of the keys to the library. He was one of those designated by the Chapter to make up the embassy to Bâle.

Very diligent in the Trial, Richard de Grouchet was cited as a witness at the time of the Rehabilitation.

He retracted his opinion, and insisted emphatically upon the constraint that Pierre Cauchon put upon the judges. He must have been about seventy at that time.
