He founded the Théâtre du Jorat in Morges in 1908, and promoted historical and rural theatre in French in Switzerland.

[3] A notable inspiration of the Jorat theater, René Morax wrote, staged and played rural and historical dramas in French.

[1] In 1910, he premiered Aliéno, written in collaboration with Gustave Doret, then in 1921 the oratorio Le Roi David with a then unknown composer, Arthur Honegger.

[6] The text, based on biblical narration, tells the story of King David from his time as a shepherd boy to his death.

[8] René Morax was also the author of little comedies and farces (including Les Quatre Doigts et le Pouce[9][better source needed][10][better source needed] in 1915, revived by the Théâtre des Faux-Nez in 1955), and of translations and adaptations which made him one of the most productive contemporary theater dramatists in Switzerland.
