Börngen and L. D. Schmadel at Tautenburg. Rahel Varnhagen von Ense (née Levin, 1771-1833) and her husband Karl August (1785-1858) were literary personalities and leading figures of Rahel's Berlin literary salon. It became a center of intellectual debate and social activity for writers. The intelligence, originality and amiability of Rahel was admired by Goethe.
