Giacomo Puccini (22 December 1858 – 29 November 1924) was an Italian composer known primarily for his operas. Regarded as the greatest and most successful proponent of Italian opera after Verdi, he was descended from a long line of composers, stemming from the late-Baroque era. Though his early work was firmly rooted in traditional late-19th-century Romantic Italian opera, he later developed his work in the realistic verismo style, of which he became one of the leading exponents.

His most renowned works are La bohème (1896), Tosca (1900), Madama Butterfly (1904), and Turandot (1924), all of which are among the most frequently performed and recorded of all operas.
