Miss Helyett is an opérette in three acts with music by Edmond Audran and words by Maxime Boucheron. It depicts the complications ensuing when the excessively puritanical heroine believes herself duty-bound to marry an unknown man who, in rescuing her from a serious fall in the Pyrenees, has been unable to avoid seeing the exposed lower half of her body.
The piece was first performed at the Théâtre des Bouffes-Parisiens on 12 November 1890. Productions followed in continental Europe, Britain, the US and Australia. The most recent revival in Paris was in 1921, and the piece remained popular in the French provinces during the next two decades, but fell out of the repertoire after that.
