Francesco (Franco) Antonio Faccio (8 March 1840 in Verona – 21 July 1891 in Monza) was an Italian composer and conductor. Born in Verona, he studied music at the Milan Conservatory from 1855 where he was a pupil of Stefano Ronchetti-Monteviti and, as scholar William Ashbrook notes, "where he struck up a lifelong friendship with Arrigo Boito, two years his junior" and with whom he was to collaborate in many ways.
Initially, he became known as the composer of two operas and, in his years (1871–1889) as music director of the Teatro alla Scala opera house, Faccio became known as a conductor of Verdi's music at La Scala, in different parts of Italy, and abroad.
After finishing his studies he began his career as a composer. His first collaboration with Boito was on a patriotic cantata, Il quattro giugno in 1860 when Boito also wrote some of the music as well as the text, and this was followed by a sequel, La sorelle d'Italia, also in the spirit of the movement towards Italian unification. With these pieces, both young men received entrees into Italian society, hence Faccio's association with Countess Maffei and the letters of introduction which followed which allowed both him and Boito access to Rossini in Paris in 1862.
Both men began work on new operas, Boito's eventually becoming Mefistofele. Faccio returned to Milan to write his first opera, I profughi fiamminghi, which was based on a text by Emilio Praga and written for La Scala where it was presented on 11 November 1863. Not a success, it survived for only five performances. However, its failure was followed by a celebratory party given for Faccio by his friends. The event included Boito's reading of the infamous "Ode saffica col bicchiere alla mano", which infuriated Giuseppe Verdi.
Faccio's second opera, Amleto, one of the many operas based on William Shakespeare's Hamlet, was written for Genoa's Teatro Carlo Felice and was given its première on 30 May 1865. The cast included some of the finest singers of the day. As Ashbrook notes, while its "innovatory libretto" was written by Boito, there was "dismay at the score's paucity of melody", but he does add that Ophelia's funeral march, the "Marcia Funebre", "[won] general approval".
