Leonie Duval

Léon Beauvallet, full name Pierre-Léon-Charles Beauvallet, (22 August 1828 – 22 March 1885) was a 19th-century French actor, playwright and novelist.
Author of numerous plays, most of them written in collaboration, as well as feuilletons published in Le Passe-Temps before publication in print, he is best known for being part of the troupe who accompanied Rachel Félix to the United-States and Cuba in 1855. The account he gave of this odyssey, first published in Le Figaro under the title Rachel et le Nouveau-Monde, had some success and was translated into English upon its release in 1856.
Léon Beauvallet was Pierre-François Beauvallet's son and Frantz Beauvallet's father, both dramatists.
