H.M.S. Pinafore in the context of "The Sorcerer"

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.

Sir William Schwenck Gilbert (18 November 1836 – 29 May 1911) was an English dramatist, librettist, poet and illustrator best known for his collaboration with composer Arthur Sullivan, which produced fourteen comic operas. The most famous of these include H.M.S. Pinafore, The Pirates of Penzance and one of the most frequently performed works in the history of musical theatre, The Mikado. The popularity of these works was supported for over a century by year-round performances of them, in Britain and abroad, by the repertory company that Gilbert, Sullivan and their producer Richard D'Oyly Carte founded, the D'Oyly Carte Opera Company. These Savoy operas are still frequently performed in the English-speaking world and beyond.

Gilbert's creative output included over 75 plays and libretti, and numerous short stories, poems and lyrics, both comic and serious. After brief careers as a government clerk and a lawyer, Gilbert began to focus, in the 1860s, on writing light verse, including his Bab Ballads, short stories, theatre reviews and illustrations, often for Fun magazine. He also began to write burlesques and his first comic plays, developing a unique absurdist, inverted style that would later be known as his "topsy-turvy" style. He also developed a realistic method of stage direction and a reputation as a strict theatre director. In the 1870s, Gilbert wrote 40 plays and libretti, including his German Reed Entertainments, several blank-verse "fairy comedies", some serious plays, and his first five collaborations with Sullivan: Thespis, Trial by Jury, The Sorcerer, H.M.S. Pinafore and The Pirates of Penzance. In the 1880s, Gilbert focused on the Savoy operas, including Patience, Iolanthe, The Mikado, The Yeomen of the Guard and The Gondoliers.

George Grossmith (9 December 1847 – 1 March 1912) was an English comedian, writer, composer, actor, and singer. His performing career spanned more than four decades. As a writer and composer, he created 18 comic operas, nearly 100 musical sketches, some 600 songs and piano pieces, three books and both serious and comic pieces for newspapers and magazines.

Grossmith created a series of nine characters in the comic operas of Gilbert and Sullivan from 1877 to 1889, including Sir Joseph Porter, in H.M.S. Pinafore (1878), the Major-General in The Pirates of Penzance (1880) and Ko-Ko in The Mikado (1885–87). He also wrote, in collaboration with his brother Weedon, the 1892 comic novel The Diary of a Nobody.

Sir Arthur Seymour Sullivan MVO (13 May 1842 – 22 November 1900) was an English composer. He is best known for 14 comic opera collaborations with the dramatist W. S. Gilbert, including H.M.S. Pinafore, The Pirates of Penzance and The Mikado. His works include 24 operas, 11 major orchestral works, ten choral works and oratorios, two ballets, incidental music to several plays, and numerous church pieces, songs, and piano and chamber pieces. His hymns and songs include "Onward, Christian Soldiers" and "The Lost Chord".

The son of a military bandmaster, Sullivan composed his first anthem at the age of eight and was later a soloist in the boys' choir of the Chapel Royal. In 1856, at 14, he was awarded the first Mendelssohn Scholarship by the Royal Academy of Music, which allowed him to study at the academy and then at the Leipzig Conservatoire in Germany. His graduation piece, incidental music to Shakespeare's The Tempest (1861), was received with acclaim on its first performance in London. Among his early major works were a ballet, L'Île Enchantée (1864), a symphony, a cello concerto (both 1866), and his Overture di Ballo (1870). To supplement the income from his concert works he wrote hymns, parlour ballads and other light pieces, and worked as a church organist and music teacher.

The D'Oyly Carte Opera Company is a professional British light opera company that, from the 1870s until 1982, staged Gilbert and Sullivan's Savoy operas nearly year-round in the UK and sometimes toured in Europe, North America and elsewhere. The company was revived for short seasons and tours from 1988 to 2003, and since 2013 it has co-produced four of the operas with Scottish Opera.

In 1875, Richard D'Oyly Carte asked the dramatist W. S. Gilbert and the composer Arthur Sullivan to collaborate on a short comic opera to round out an evening's entertainment. When that work, Trial by Jury, became a success, Carte put together a syndicate to produce a full-length Gilbert and Sullivan work, The Sorcerer (1877), followed by H.M.S. Pinafore (1878). After Pinafore became an international sensation, Carte jettisoned his difficult investors and formed a new partnership with Gilbert and Sullivan that became the D'Oyly Carte Opera Company. The company produced the succeeding ten Gilbert and Sullivan operas and many other operas and companion pieces, mostly at the Savoy Theatre in London, which Carte built in 1881 for that purpose. The company also mounted tours in Britain, New York and elsewhere, usually running several companies simultaneously. Carte's able assistant, Helen Lenoir, became his wife in 1888 and, after his death in 1901, she ran the company until her own death in 1913. By this time, it had become a year-round Gilbert and Sullivan touring repertory company.

Thespis, or The Gods Grown Old, is an operatic extravaganza that was the first collaboration between dramatist W. S. Gilbert and composer Arthur Sullivan. No musical score of Thespis was ever published, and most of the music has been lost. Gilbert and Sullivan went on to become the most famous and successful artistic partnership in Victorian England, creating a string of enduring comic opera hits, including H.M.S. Pinafore, The Pirates of Penzance and The Mikado.

Thespis premièred in London at the Gaiety Theatre on 26 December 1871. Like many productions at that theatre, it was written in a broad, burlesque style, considerably different from Gilbert and Sullivan's later works. It was a success, for a Christmas entertainment of the time, and closed on 8 March 1872, after a run of 63 performances. It was advertised as "An entirely original Grotesque Opera in Two Acts".
