Assen or Asen Hartenau [a] (16 January 1890 – 15 March 1965), in his early life styled as the Count of Hartenau, was an Austrian civil servant and the son of the deposed Bulgarian prince Alexander of Battenberg ( r. 1879–1886).


Early life

Assen Hartenau was born in Graz [3] on 16 January 1890, [1] [4] the son and eldest child of Alexander of Battenberg, deposed Prince of Bulgaria ( r. 1879–1886), and his wife Johanna Loisinger, an actress and singer. [4] He was named after the medieval Bulgarian ruler Ivan Asen I ( r. 1188–1196), [4] [5] co-founder of the Second Bulgarian Empire (1185–1422). [5] The name thus served to underline the claims of Alexander and his family to the Bulgarian throne. [5]

Hartenau had a younger sister, Svetana (1893–1935). [2] [4] After Alexander's early death in 1893, [4] Johanna and the children moved to Vienna. The family was in exile provided with a yearly pension of 50,000 leva by the Bulgarian government. [2] [6] Following Alexander's deposition and marriage to Johanna, he had styled himself as the Count of Hartenau, [7] a title inherited by Assen. [4]


Hartenau studied law at the University of Graz [8] and eventually became a Doctor of Law. [2] He eventually dropped the title of count and became an Austrian civil servant. [4] Through his life he held various important financial and political positions in Austria. [2] [8] He was employed in the Ministry of Finance from 1919 to 1922 and served as a diplomat in Paris from 1922 to 1928, mainly overseeing payment of war reparations. [2] In 1938, Hartenau was made the State Commissioner of the Oesterreichische Nationalbank. [9] He played an important role in settling the Austrian national debt in the 1940s. [10]

After World War II (1939–1945), Hartenau was deemed to have been "politically indifferent" during the war. [10] From 1951 to 1953, he served as the financial director of Zellwolle Lenzing AG. [2] Hartenau died in Vienna [11] on 15 March 1965. [2] [11]

Personal life

Hartenau married Bertha Hussa-Lamos (1892–1971) on 7 May [2] 1934. [4] The couple did not have any children together, [2] though Hartenau adopted Hussa-Lamos's son Wilhelm (from a previous marriage), who thus became Wilhelm Hartenau (1915–1991). [2] [4] Wilhelm was a physician in Vienna and had three children of his own; Alexander, Elizabeth and Francisca, [4] regarded as the heirs of Alexander of Battenberg. [2] [12] [b]

During the reign of Alexander's successor in Bulgaria, Ferdinand I ( r. 1887–1918), the Bulgarian press sometimes highlighted Hartenau as a legitimate possible rival contender for the throne, styling him as "Prince" and as "His Highness". [13]


  1. ^ Different sources ascribe Hartenau slightly different full names. Two variants are Louis Alexander Assen, Count of Hartenau [1] and Krum Asen Louis Alexander von Hartenau. [2]
  2. ^ Given that Hartenau's sister Svetana did not have any biological children either, Alexander of Battenberg otherwise has no living descendants. [2]
