Anne Louise Brillon de Jouy (née Boyvin d'Hardancourt; 13 December 1744 – 5 December 1824) was a French musician and composer. Born in Paris, she lived in Passy and played and composed for the harpsichord and the piano. She learned to play the harpsichord as a child. Life Her parents were Marie-Élisabeth, (née Martin) (1723-1785) and Louis-Claude Boyvin d'Hardancourt (c. 1710–1756), a royal tax clerk. In October 1763 Anne Louise married tax clerk Jacques Brillon de Jouy (1722-1787), 22 years her elder. They had two daughters, Cunégonde and Aldegonde. Cunégonde went on to marry the General Antoine Marie Paris d'Illins. She died at Villers-sur-Mer, Calvados, aged 79. Career Every Wednesday and Saturday Anne Louise held a salon at her house in the country in Passy, which became a permanent fixture. Foreign musicians passing through Paris performed with her. In doing so, she acquired an excellent reputation as a musician and composer, despite not performing publicly or having any of her compositions published. Several composers dedicated sonatas to her, including Johann Schobert, Luigi Boccherini, Charles Burney, Ernst Eichner, and Henri-Joseph Rigel. Her compositions number almost 90. Most are instrumental chamber music, including solo and accompanied keyboard sonatas; sonatas for cello, violin or harp; trios for two harpsichords and piano; and vocal music. She wrote music to perform herself and with the two Brillon daughters, Cunégonde and Aldegonde. The piano music written for her own performance is virtuosic, incorporating new keyboard techniques and sonorities, along with a number of innovations usually associated with later pianist-composers such as Czerny and Liszt. Her manuscripts are in a private French collection and in the American Philosophical Society library in Philadelphia. When Benjamin Franklin arrived in Paris in 1777 as ambassador from the American colonies, he lived near the Brillon residence and was a welcome guest at her distinguished salon, which he described as 'my Opera', where there are 'little Concerts' with music and singing. After his return to America in 1785, he and Mme Brillon maintained an active correspondence. In 1767, Boccherini composed in Paris his Six Sonatas for Pianoforte and Violin op 5. The set was dedicated to Anne Louise Brillon: Madame, I have never before composed for the keyboard; I heard you play on that instrument, and then I wrote these sonatas; the homage that I offer you through them is, simultaneously, a fitting tribute, and one of reconnaissance; you have inspired them,
