Simon Le Duc, more commonly Leduc (Paris, 15 January 1742 – 22 January 1777), was a French violinist, soloist at the Concert Spirituel, music publisher and composer.
Leduc was a pupil of the famous violinist and professor at the Paris Conservatoire, Pierre Gaviniès.
He later became director of the Concerts Spirituel, with Gaviniès and François-Joseph Gossec During the child prodigy Wolfgang Amadeus Mozart's first tour of Europe in 1763–64, Wolfgang and his father Leopold Mozart had a chance to hear Leduc play.
In his survey of music of the galant period, Robert Gjerdingen notes strong similarities between Leduc's style and that of his Neapolitan contemporaries, especially Cimarosa.
[3] Gjerdingen writes, "Leduc wrote highly refined music for small aristocratic gatherings in chambers and salons.
