Guillaume de la Chambre the younger, de Camera, was born about 1403, and became licentiate in medicine on March 6, 1430, and immediately became a teacher on the faculty.
He was still a regent in November, 1452.

He was the son of Guillaume, physician to the Queen, and sold, in 1430, to the Norman "Nation" a house that he owned in the rue Galande in common with his brother Jean, Esquire.

An assiduous judge at the Trial, Guillaume de la Chambre visited Jeanne as physician and he was present at her execution.

He testified at the time of the Rehabilitation that his decision was torn from him by the Bishop of Beauvais. His testimony, entirely favorable to the Maid, is that of a clear-sighted and intelligent mind.
