Jean Tiphaine won second place among twelve candidates for the licentiate in medicine on February 27, 1418, and became a member of the Faculty of Medicine in November.

He was chaplain of Saint Aignan in the château of Caen, canon of the Sainte Chapelle in Paris, and was received as canon of the cathedral of Rouen in 1432- Jean Tiphaine never resided in Rouen, but at Paris, where he filled the commissions of his colleagues.

His death was announced to the Chapter in February, 1469.

Tiphaine testified at Paris for the Rehabilitation and denied having formulated the sentence which, however, we possess. He had attended her in prison, and his memory was in other ways faithful, for he described with exactness Jeanne's prison in the tower of Rouen castle and reported the Maid's words.
