Assing. I. Rosa Maria, a German poetess, sister of Varnhagen von Ense, born in Diissel-dorf, May 28, 1783, died Jan. 22, 1840. The outbreak of the French revolution obliged her family to take up their residence in Strasburg, and in 1796 they removed to Hamburg. After the death of her father in 1799 she became a teacher. In 1816 she married Dr. Assing, a physician of Konigsberg, who on her account removed to Hamburg, where his house became a favorite place of literary reunion. The poet Chamisso was a frequent visitor. Rosa's poems have been published, with a memoir of her life, under the title of Rosa Maria's poetischer Nachlass (Altona, 1841). II. Ludmilla, daughter of the preceding, born at Hamburg, Feb. 22, 1827. After the death of her parents she resided in Berlin with her uncle, the celebrated Varnhagen von Ense, occupying a daughter's place in his house, and receiving an unusually complete education. She first published essays in newspapers and reviews, and in 1857 produced a biography of the countess Elisa von Ahlefeldt. Several other biographies followed from her pen.

On the death of her uncle she edited the unpublished portion of his Denkwurdiglceiten, issuing the 8th and 9th volumes in 1859. In 1860 she also published Alexander von Humboldt's letters to her uncle, and in 1861-'2 the diaries of Varnhagen von Ense himself. The manner in which political events are treated in this collection brought her into disfavor with the court, and in May, 1862, an action was begun against her in Berlin - she having in the autumn of 1861 taken up her residence in Florence - which resulted in her conviction as a traducer of the king, queen, and various personages, and in her sentence to eight months' imprisonment. A similar trial, and sentence to two years' imprisonment, followed the publication of the remaining volumes of the collection in 1864; but she never actually underwent these punishments. She has since translated much from the Italian.
