Jean Guitton (1901-1999), was also a philosophy graduate of the ENS, like Couchoud, and a disciple of Henri Bergson (yet another philosophy graduate of the ENS, and a 1927 Nobel Prize for Literature, 1859-1941). Guitton was a French Catholic philosopher interested in mysticism, and a friend of Couchoud. Guitton interceded with the local archbishop to overcome the resistance of the mystic's Catholic priest who was her "spiritual director" and allow visits by Couchoud. Guitton described his last conversation with Couchoud, discussing the mystic on the quay of the Vienne train station, when Couchoud recited a short poem about the mystic.
