"La Motte Fouqué's Undine"

 Friedrich Heinrich Karl de la Motte, Baron Fouqué (1777 - 1843), was a German writer of romantic and fantasy stories. His most famous work is Undine, a tale based on that of Melusine, and also in part resembling The Little Mermaid. It has been called 'the most beautiful' of all fairytales. Compare the real-life name of 'la Motte' in connection with a Melusine-like tale to the fictional LaMotte in Possession.
