Louis-Nicolas Brette Saint-Ernest
Louis-Nicolas Brette Saint-Ernest (3 May 1802 – 10 March 1860) was a 19th-century French actor and playwright.

Biography 
A master study in Paris and assistant bricklayer, he began acting in 1829 before being hired in 1832 by the Théâtre de la Porte-Saint-Martin. He then played for the Théâtre de l'Ambigu-Comique from 1837 to 1852. He often appeared in the role of the father in many sentimental plays. 

Most of the time, his own plays that he signed Saint-Ernest, were presented at the Théâtre de l'Ambigu-Comique, of which he was managing director from 1848 to 1852. In 1852, he became dramaturge on the stage of the théâtre du Cirque, a position he still held when he died in 1860.
