Le docteur Miracle (Doctor Miracle) is an opérette in one act. The libretto, by Léon Battu and Ludovic Halévy, is based on Sheridan's play Saint Patrick's Day. Bizet wrote the work when he was just 18 years old for a competition organised by Jacques Offenbach. He shared first prize with Charles Lecocq, 6 years his senior. Their reward was to have both pieces performed at Offenbach's Bouffes-Parisiens theatre. The premieres took place on 9 April 1857 and although neither opera was a palpable hit both were performed 11 times before falling into oblivion. It seems that public opinion favoured Lecocq - now we can all be judge and jury.
