Guillaume Louis Cottrau

Guillaume Louis Cottrau (10 August 1797 in Paris – 31 October 1847 in Naples) was a French composer and music publisher.

Arrived in Naples with his father who served Joachim Murat, the King of Naples, Cottrau undertook the publication of Passatempi musicali, a collection of Neapolitan songs, some of his compositions. Thanks to this, the genre crossed the borders of the kingdom and reached great diffusion and popularity abroad.

One of his themes was taken up by Franz Liszt for his Tarentelle napolitaine included in the Années de pèlerinage.

Guglielmo was the father of composer Teodoro Cottrau.
