Jean Nicolas Bouilly

Jean-Nicolas Bouilly (24 January 1763 – 14 April 1842) was a French playwright, librettist, children's writer, and politician of the French Revolution. He is best known for writing a libretto, supposedly based on a true story, about a woman who disguises herself as a man to rescue her husband from prison, which formed the basis of Beethoven's opera Fidelio as well as a number of other operas.
