Léon Jonathan
Léon Jonathan was a 19th-century French playwright and chansonnier.

Biography 
His plays were presented at the Théâtre Beaumarchais and the Théâtre du Château-d'Eau. He met great success with his plays Pierre Vaux, l'instituteur  and Carnot, a 5-act drama given on the stage of the Théâtre de l'Ambigu in 1884. Then no further mention of him is known. It is possible, judging by the contentious parts of his plays that the name was a non yet elucidated pseudonym.
