François de Fossa
François de Fossa (1775 – 1849) was a French guitarist and composer. Fossa was not only a friend of Dionisio Aguado but also helped Aguado write his Method and arranged for its publication in France. (Aguado lived with Fernando Sor in Paris from 1826 to 1837, during which time he also met Fossa.) Fossa also had a hand in copying Luigi Boccherini’s guitar quintets and arranging them for publication.
Fossa wrote a handful of important solo guitar works, but he is most well known for his chamber music, especially his trios Op. 18.
