Giovacchino Forzano was an Italian playwright, librettist, stage and film director. A resourceful writer, he authored numerous popular plays and produced opera librettos for most of the major Italian composers of the early twentieth century, including the librettos for Giacomo Puccini's Suor Angelica and Gianni Schicchi.

Giacomo Puccini 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.
