Fanny Tacchinardi Persiani (Italian pronunciation: [ˈfanːi takːiˈnardi perˈsjani]) (4 October 1812 – 3 May 1867) was an Italian soprano particularly associated with bel canto composers, such as Rossini, Donizetti, Bellini, and early Verdi. Her 'golden' period in Paris and London was between 1837 and 1848.
Born in Rome, Fanny Tacchinardi was the daughter of cellist and tenor Nicola Tacchinardi, a very eminent teacher of vocal technique who trained her voice from childhood. In 1830 she married the composer Giuseppe Persiani (1799–1869), and as she embarked on her stage career she added his surname to her own. She made her stage début at Livorno in Giuseppe Fournier-Gorre's Francesca da Rimini in 1832. She soon appeared in Venice, Florence, Milan, Naples, and other Italian cities, in Tancredi, La gazza ladra, Il pirata, L'elisir d'amore and other operas.
Donizetti heard her in 1833, and described her voice as "rather cold, but quite accurate and perfectly in tune." He chose her to create title roles in three of his operas, Rosmonda d'Inghilterra with Gilbert Duprez as Enrico II (at Florence in February 1834),Pia de' Tolomei (Venice, 1837, a work conceived expressly for her from the beginning), but most notably that of Lucia in Lucia di Lammermoor in Naples in 1835, one of the immortal roles of Romantic opera. Duprez was her Edgardo. Donizetti (remarking that she was "not the brightest star") told in a letter how in rehearsal she made an almighty row (which terrified Duprez) because, after Lucia's finale (the Mad Scene) there remained the finale of Edgardo ('Fra poco a me ricovero') before the curtain fell, displacing the final applause from herself to the tenor. She also sang Lucia in the first Paris performance, in December 1837, opposite Rubini (for whom Edgardo became one of his most celebrated roles), a performance received with acclaim bordering on hysteria. She was furthermore in the London premiere in April 1838.
