Gioachino Antonio Rossini (February 29, 1792 – November 13, 1868) was a popular Italian composer who created 39 operas as well as sacred music and chamber music. His best known works include Il barbiere di Siviglia (The Barber of Seville), La Cenerentola and Guillaume Tell (William Tell).

Rossini's most famous opera was produced on February 20, 1816 at the Teatro Argentina in Rome. The libretto by Cesare Sterbini, a version of Pierre Beaumarchais' infamous stage play Le Barbier de Séville, was the same as that already used by Giovanni Paisiello in his own Barbiere, an opera which had enjoyed European popularity for more than a quarter of a century. Much is made of how fast Rossini's opera was written, scholarship generally agreeing upon two weeks. Later in life, Rossini claimed to have written the opera in only twelve days. It was a colossal failure when it premiered as Almaviva; Paisiello’s admirers were extremely indignant, sabotaging the production by whistling and shouting during the entire first act. However, not long after the second performance, the opera became so successful that the fame of Paisiello's opera was transferred to Rossini's, to which the title The Barber of Seville passed as an inalienable heritage.
