Kurt Weill was known for producing the opera adapted from which 18th century English opera?
The Threepenny Opera The Threepenny Opera (Die Dreigroschenoper ) is a "play with music" by Bertolt Brecht and Elisabeth Hauptmann, adapted from John Gay's 18th-century English ballad opera, "The Beggar's Opera", with music by Kurt Weill and insertion ballads by François Villon and Rudyard Kipling. Although Hauptmann produced 80 to 90 percent of the text, Brecht suppressed this and assumed sole credit, and is usually listed as sole author in printed versions.
Gaetano Martinelli Gaetano Martinelli (? – 1802) was an Italian librettist active in the court theatres of Charles Eugene, Duke of Württemberg from 1766 to 1769 and in Lisbon as the court poet to Joseph I of Portugal and his daughter Maria I from 1769 until his death in 1802. He was one of a group of reforming Italian librettists which also included Calzabigi, Verazi, and Migliavacca, who moved away from the traditional Metastasian plot structures that had dominated opera during the first half of the 18th century. The majority of his early libretti were for comic ("opera buffa") or semi-comic ("dramma giocoso") operas.
