Georges Barbarin (1882–1965) was a French poet, journalist, and prolific author best known for his works on spirituality, personal development, and esoteric topics such as pyramidology and mystical symbolism. His meeting with Grace Gassette in the 1930s led to a spiritual partnership culminating in their collaborative work La Clé, which became influential in France.
His description of Grace Gassette during her later years in France is worth quoting in full, as it provides a vivid and insightful glimpse into her way of life and the spiritual path she had fully embraced after acquiring the Prieuré of Bazainville.
