Gertrud von Le Fort (1876-1971)

Gertrud von Le Fort was a German writer of novels, poems, and essays. She came from a Protestant background, but converted to Catholicism in 1926. Most of Gertrud’s writings come after this conversion. Her novel Die Letze am Schafott (The Song at the Scaffold), by far her most famous work, was the basis for Dialogues of the Carmelites. It’s the story of the sixteen Carmelite martyrs who were guillotined during the French Revolution.
