Gioachino Antonio Rossini (February 29, 1792 – November 13, 1868) was an Italian composer who wrote operas, as well as some sacred music, songs, chamber music and piano pieces.

A precocious composer of operas, he made his full debut at the age of eighteen (with La cambiale di matrimonio). His best-known operas include the Italian comedies Il barbiere di Siviglia (The Barber of Seville), L’italiana in Algeri (The Italian Girl in Algiers) and La Cenerentola (Cinderella). He also wrote a string of serious operas in Italian, including works such as Tancredi, Otello and Semiramide. The semi-serious opera La Gazza Ladra (The Thieving Magpie) has one of Rossini’s most celebrated overtures. After moving to Paris in 1824, he eventually started to write in French. His last opera, the epic Guillaume Tell (William Tell), replete with its iconic overture, helped usher in grand opera in France.
