Edouard Dermit was the adopted son of the heir of French author and film director Jean Cocteau (1889-1963). He acted in three of his father's films: Orphee, Les Enfants Terribles and Testament of Orpheus. In 1965 he finished the chapel to Notre Dame de Jerusalem which Cocteau had designed for the town of Frejus. Later on he worked as an antiques appraiser in Paris.
