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.
