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. In 1770 she married the architect Victor Louis. 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.
