thumb|Portrait of Karl August Varnhagen von Ense by [[Samuel Friedrich Diez.]]

Karl August Varnhagen von Ense (21 February 1785 in Düsseldorf – 10 October 1858 in Berlin) was a German biographer, diplomat and soldier.

Life and career

He was born in Düsseldorf, the younger brother of Rosa Maria Varnhagen, a noted poet, writer, and educator. He studied medicine in Berlin, but most of his time was spent examining philosophy and literature, which he later studied more thoroughly at Halle and Tübingen. He began his literary career in 1804 working along with Adelbert von Chamisso on his Berliner Musenalmanach.

In 1809, he joined the main Austrian army under Archduke Charles, serving in IR47 Vogelsang at the Battle of Wagram, where he was wounded on the first day, 5 July. He was then made adjutant to Prince Bentheim, whom he accompanied to Paris, where he continued his studies. In 1812, he entered the Prussian civil service in Berlin but soon left to enter the Russian service as captain. He served in Tettenborn's corps as adjutant to Tettenborn on trips to Hamburg and Paris. He recorded his experiences in Geschichte der Hamburger Ereignisse (History of the events in Hamburg; London, 1813) and Geschichte der Kriegszüge Tettenborns (History of Tettenborn's Campaigns, 1814).

On 10 October 1858, while playing chess with his niece, Karl August Varnhagen von Ense died of unknown causes. His last words, shortly before his death, were, "I lost."

Writings

Although he developed a reputation as an imaginative and critical writer, he is most famous as a biographer. He possessed a remarkable ability to group facts together and to bring out their essential significance. His style is distinguished for its strength, grace and purity. Among his principal works are:

  • Goethe in den Zeugnissen der Mitlebenden (1824)
  • Biographische Denkmäler (5 vols., 1824–30; 3rd edition, 1872)
  • Biographies of General von Seydlitz (1834), Field-Marshal Gebhard Leberecht von Blücher, victor over Napoleon at Waterloo, Sophia Charlotte, Queen of Prussia (1837), Field-Marshal Schwerin (1841), Field-Marshal Keith (1844), and General Bülow von Dennewitz (1853)

His Denkwürdigkeiten und vermischte Schriften appeared in nine volumes in 1843–59, the last two volumes appearing after his death. His niece, Ludmilla Assing, between 1860 and 1867, edited several volumes of his correspondence with eminent men and his Tagebücher (14 vols., 1861–70). Blätter aus der preussischen Geschichte appeared in five volumes (1868–69); his correspondence with his wife, Rahel, appeared in six volumes in 1874–75; and that with Carlyle in 1892.
