L ' elisir d ' amore, a comedy produced in 1832, came soon after, and is deemed one of the masterpieces of 19th-century opera buffa ( as is his Don Pasquale, written for Paris in 1843 ).

He changed the location and names to the final Norwegian version while the opera was in rehearsals for its first production, which took place in Dresden in January 1843 with Wagner himself conducting.

Its first performance in Vienna was at the Kärtnertortheater on 14 May 1843, a production in which Donizetti participated and added the comic baritone duet " Cheti, cheti, immantinente " from a discarded portion of his unperformed opera L ' ange de Nisida.

He then moved to Paris, presenting Le puits d ' amour ( 1843 ) in early 1843, followed by his opera based on Les quatre fils Aymon ( 1844 ) for the Opéra-Comique ( also popular in German-speaking countries for many years as Die Vier Haimonskinder ) and L ' étoile de Seville ( 1845 ) for the Opéra.

The subject was well known and had been used by other composers, including Daniel Auber, for his 1833 opera, Gustave III, ou Le bal masqué and later by Saverio Mercadante for his Il reggente in 1843.

At the same time as his successes in Paris, Meyerbeer, as a Prussian Court Kapellmeister ( Director of Music ) from 1832, and from 1843 as Prussian General Music Director, was also influential in opera in Berlin and throughout Germany.

However, from the early 1840s, as Wagner developed Tannhäuser and Lohengrin, his ideas on opera increasingly diverged from Meyerbeerean standards ; even in 1843 Wagner had written to Schumann condemning Meyerbeer's work as ' a striving after superficial popularity '.

His eldest daughter, Francesca ( Cecchina ), married the pianist Sigismond Thalberg in 1843, and his younger daughter, Therese, married the opera singer Hans von Rokitansky.

Richard Wagner's opera, The Flying Dutchman ( 1843 ) is adapted from an episode in Heinrich Heine's satirical novel The Memoirs of Mister von Schnabelewopski ( Aus den Memoiren des Herrn von Schnabelewopski ) ( 1833 ), in which a character attends a theatrical performance of The Flying Dutchman in Amsterdam.

The initial lack of enthusiasm for this Russian-inspired production has been attributed to the St. Petersburg's audience's growing taste at the time for Italian opera, which was so pronounced that in 1843, Tsar Nicholas I established an Italian opera company in the Bolshoi Kamenniy Teatr, and the Russian opera company lost its home.

Gaetano Donizetti's tragic opera Maria di Rohan, which debuted at the Kärntnertor theater in Vienna on 5 June 1843, followed by a success in Paris in November, was freely based on the conspiracy of Chalais.
