She met Franz Liszt the next year.
In 1866, she met emperor Napoleon III and befriended him.
After his defeat at the Battle of Sedan, she visited him for a last time when he was a prisoner of the Prussians at Schloss Wilhelmshöhe and consoled him playing music.
She later wrote a book about their four-year relationship, "The Last Love of an Emperor".
In the early 1880s, she developed an interest in Russian music.
This led to her studying the Russian language, translating some vocal music by several Russian composers, and arranging concerts and recitals of their music.
Her advocacy of music by The Mighty Handful favored that of César Cui and facilitated the production of the latter's opera "Prisoner of the Caucasus" in Liège in 1886.
Cui's collection of piano pieces entitled "À Argenteau" is a musical reminiscence of the count and countess' estate in Belgium.
La Comtesse de Mercy-Argenteau died of cancer on 8 November 1890 in Saint Petersburg, Russia.

Barbu Știrbey
Prince Barbu Alexandru Știrbey (4 November 1872 – 24 March 1946) was 30th Prime Minister of the Kingdom of Romania in 1927.
He was the son of Prince Alexandru Știrbey and his wife Princess Maria Ghika-Comănești, and grandson of another Barbu Dimitrie Știrbei (born Bibescu, adopted Știrbei), who was Prince of Wallachia and died in 1869.
He married his second cousin, Princess Nadèje Bibescu in 1895, daughter of Prince Gheorge Bibescu and Marie Henriette Valentine de Caraman-Chimay, daughter of Prince Joseph de Riquet de Caraman-Chimay.
They had four daughters: Maria, Nadejda, Elena and Catharina.
His real significance in Romania history arises from his role as close confidant of Queen Marie, who was herself a highly influential figure in Romanian government circles prior to the accession of her son King Carol II to the throne in 1930.
Știrbey and Queen Marie were lovers, and Ştirbey was probably the father of her youngest child, Mircea, and possibly the father of Ileana .
Shortly after the Royal coup of August 23, 1944, he traveled to Moscow with the Romanian delegation that signed on September 12 the Armistice Agreement between Romania and the Soviet Union.

Émilie Pellapra
Émilie Pellapra( 11 November 1806 – 22 May 1871)," comtesse de Brigodeprincesse de Chimay", was the daughter of Françoise- Marie LeRoy and possibly Napoleon I of France.
She claimed to be the product of her mother's affair with the French Emperor which supposedly took place in April 1805, but this date is incompatible with Émilie's birth in November 1806.
She was married firstly to Count Louis- Marie of Brigode( 1777 – 1827) and married secondly to Prince Joseph de Riquet de Caraman( 1808 – 1886), 17th prince de Chimay.
Émilie Louise Marie Françoise Joséphine Pellapra was born in Lyon on November 11, 1806, the daughter of Madame Pellapra, née Françoise- Marie LeRoy, herself the wife of a rich financier named Henri( de) Pellapra.
Émilie may have been the illegitimate daughter of Napoleon I, as she claimed to be.
Emilie Pellapra made it clear she was the natural daughter of Napoleon.
This would have to have been the result of an affair with her mother at the time of a stay by Napoleon in Lyon.
Her claim was that an affair took place in April 1805, whilst Napoleon was on the way to Italy to be crowned, but this date is incompatible with Émilie's birth of in November 1806.
For Émilie to have been the daughter of Napoleon it would have been necessary that he stayed in Lyon in February 1806.
However, no stay in this city at that time seems to have taken place and, according to several authors( in particular André Gavoty in the Bulletin de l' Institut Napoleon April 1950), Napoleon only met LeRoy in 1810.
Emilie Pellapra married
Count Louis Marie de Brigode who died shortly after, though they had twins:
She remarried on 30 August 1830 to Prince Joseph de Riquet de Caraman( 1808- 1886), 17th prince de Chimay, son of Prince François- Joseph- Philippe de Riquet and Thérésa Cabarrus, and had four children:
She died at the Château de Menars on May 22, 1871.
