Fidelio is a German opera with spoken dialogue in two acts by Ludwig van Beethoven. It is his only opera. The German libretto is by Joseph Sonnleithner from the French of Jean-Nicolas Bouilly, which had been used for the 1798 opera Léonore, ou L’amour conjugal by Pierre Gaveaux, and the 1804 opera Leonora by Ferdinando Paer . The opera tells how Leonore, disguised as a prison guard named "Fidelio", rescues her husband Florestan from death in a political prison.The above text is a snippet from Wikipedia: Fidelio
