Marie Emmanuelle Bayon Louis

Marie-Emmanuelle Bayon Louis (6 June 1745, Marcei – 29 March 1825, Aubevoye) was a French composer, pianist, and salonnière.

Contemporaries credited Mlle Bayon (or Baillon) for making the fortepiano popular in France.

[2] Her surviving works are, as Bayon, a collection of six keyboard sonatas, three of them with violin accompaniment, opus 1 (1769), and, as Louis, the two-act opéra-comique, Fleur d’épine ("May-Flower"), first performed in 1776.

1 sonatas Bayon's reference to "the many kindnesses bestowed upon me since my tenderest infancy" by the family of Madame la Marquise de Langeron suggests that her musical training came through such patronage.

After Bayon's marriage, the Louis residence became the site of a highly select salon.
