Daniel Stern

Marie Catherine Sophie, Comtesse d'Agoult (born de Flavigny; 31 December 1805 – 5 March 1876), was a French romantic author and historian, known also by her pen name, Daniel Stern.

Early life

Marie d'Agoult was born in Frankfurt am Main, Germany, with the full name of Marie Catherine Sophie de Flavigny, the daughter of Alexandre Victor François, Vicomte de Flavigny (1770–1819), an émigré French aristocrat, and his wife Maria Elisabeth Bethmann (1772–1847), whose father was the German merchant and banker Johann Philipp Bethmann (1715–1793). According to Siegfried Mandel, however, Maria Elisabeth's father was Simon Moritz Bethmann, who was Johann Philipp's younger brother, and the Bethmanns were Jewish. The young Marie spent her early years in Germany and completed her education in a French convent after the Bourbon Restoration.

She entered into an early marriage of convenience with Charles Louis Constant d'Agoult, Comte d'Agoult (1790–1875) on 16 May 1827, thereby becoming the Comtesse d'Agoult. They had two daughters, Louise (1828–1834) and Claire (1830–1912). Marie never divorced the count, even though she had left him for Franz Liszt.

Franz Liszt

From 1835 to 1839, she lived with composer and virtuoso pianist Franz Liszt, who was six years younger, and was then a rising concert star. Liszt dedicated “Die Lorelei", one of his very first pieces to her.

From 1837 to 1839 the two traveled to Italy and Switzerland, staying successively in Bellagio, Milan, Venice, Lugano, Modena, Florence, Bologna and Rome. During these travels, she became close to Liszt's circle of friends, including Frédéric Chopin, who dedicated his 12 Études, Op. 25 to her, and George Sand.
