Artaria's most important early collaboration was with the Austrian composer
Joseph Haydn, who published more than 300 works through them, including many of the composer's
string quartets (such as the
Opus 33), which were a popular seller. The value of Haydn's works helped push Artaria to the top of the music publishing world in the late 18th century. This important relationship helped Artaria secure the rights to the works of other important classical composers such as
Luigi Boccherini and, most notably,
Wolfgang Amadeus Mozart. During his lifetime, Artaria was Mozart's principal publisher, although after his death this passed to the German house of
Breitkopf & Härtel. Starting in 1793, Artaria published several early works of
Ludwig van Beethoven, until a bitter dispute over the publishing rights of Beethoven's
String Quintet Op. 29 which culminated in a court case from 1803 until 1805. Yet, Artaria also published Beethoven's
Hammerklavier Sonata in 1819 and Carlo's nephew Matthias (1793–1835) published the composer's
Große Fuge in 1827. Other important names that had works published by Artaria include
Gluck,
Clementi, and
Salieri. == Legacy ==
