W. S. Gilbert was an English dramatist, librettist, poet and illustrator best known for his collaboration with he composer Sir Arthur Sullivan on a series of comic operas (known as the Savoy operas). The most famous of these are H.M.S. Pinafore, The Pirates of Penzance and The Mikado. His creative output included over 75 plays and libretti, numerous stories, poems, lyrics, the Bab Ballads (an extensive collection of light verse accompanied by his own comical drawings) and various other comic and serious pieces.
Gilbert's plays and realistic style of stage direction inspired other dramatists, including Oscar Wilde and George Bernard Shaw. According to The Cambridge History of English and American Literature, Gilbert's 'lyrical facility and his mastery of metre raised the poetical quality of comic opera to a position that it had never reached before and has not reached since.'
