Libretti in the context of "Cognates"

Gilbert and Sullivan were a Victorian-era theatrical partnership of the dramatist W. S. Gilbert and composer Arthur Sullivan. The two men collaborated on fourteen comic operas between 1871 and 1896, of which H.M.S. Pinafore, The Pirates of Penzance and The Mikado are among the best known. The producer Richard D'Oyly Carte brought Gilbert and Sullivan together and nurtured their collaboration. He built the Savoy Theatre in 1881 to present their joint works (which came to be known as the Savoy Operas) and founded the D'Oyly Carte Opera Company, which performed and promoted Gilbert and Sullivan's works for more than a century.

Gilbert, who wrote the witty, satiric libretti for these operas, created fanciful "topsy-turvy" worlds where each absurdity is taken to its logical conclusion: fairies rub elbows with British lords, flirting is a capital offence, gondoliers ascend to the monarchy, and pirates emerge as noblemen who have gone astray. Sullivan, six years Gilbert's junior, composed the music, contributing memorable melodies that could convey both humour and pathos.

Giacomo Meyerbeer (born Jakob Liebmann Meyer Beer; 5 September 1791 – 2 May 1864) was a German opera composer, "the most frequently performed opera composer during the nineteenth century, linking Mozart and Wagner". With his 1831 opera Robert le diable and its successors, he gave the genre of grand opera 'decisive character'. Meyerbeer's grand opera style was achieved by his merging of German orchestra style with Italian vocal tradition. These were employed in the context of sensational and melodramatic libretti created by Eugène Scribe and were enhanced by the up-to-date theatre technology of the Paris Opéra. They set a standard that helped to maintain Paris as the opera capital of the nineteenth century.

Born to a wealthy Jewish family, Meyerbeer began his musical career as a pianist but soon decided to devote himself to opera, spending several years in Italy studying and composing. His 1824 opera Il crociato in Egitto was the first to bring him a Europe-wide reputation, but it was Robert le diable (1831) which raised his status to great celebrity. His public career, lasting from then until his death, during which he remained a dominating figure in the world of opera, was summarized by his contemporary Hector Berlioz, who claimed that he 'has not only the luck to be talented, but the talent to be lucky.' He was at his peak with his operas Les Huguenots (1836) and Le prophète (1849); his last opera (L'Africaine) was performed posthumously. His operas made him the most frequently performed composer at the world's leading opera houses in the nineteenth century.

Charles Jennens (1700 – 20 November 1773) was an English landowner and art patron. As a friend of Handel, he helped author the libretti of several of his oratorios, most notably Messiah.
