Emmerich Joseph Wolfgang Heribert de Dalberg, 1st Duke of Dalberg (31 May 1773 – 27 April 1833) was a German diplomat who was elevated to the French nobility in the Napoleonic era and who held senior government positions during the Bourbon Restoration.
After the Treaty of Vienna in 1809, Dalberg was naturalized as a French citizen and charged with negotiating Napoleon's marriage with Marie Louise of Austria. On 14 April 1810, he was created a duke of the Empire as duc de Dalberg. He was made a Councilor of State on 14 October 1810, with a large endowment. When Talleyrand was disgraced, he also fell from favor.[1]
Dalberg left France during the Hundred Days, when Napoleon returned from exile, and he returned after the second Bourbon Restoration. On 17 August 1815, he was made a Peer of France and Minister of State. On 26 January 1816, he was appointed ambassador to Turin. In the chamber of peers, he showed himself in favor of the Charter of 1814.[1]
Towards the end of the Restoration, he retired to his castle, Schloss Herrnsheim, where he died on 27 April 1833.[2] His daughter, Marie Louise von Dalberg (1813–1860), married Sir Ferdinand Acton, 7th Baronet, who assumed the additional surname of Dalberg. After Sir Ferdinand's death in 1837, she married Granville Leveson-Gower (who became the 2nd Earl Granville in 1846).
