自由劇場
Antoine founded the Théâtre Libre in Paris in 1887. This was a "théâtre d'essai", a workshop theatre, where plays were produced whether they would perform at the box office or not. It was also a stage for new writing whose subject matter or form had been rejected in other theatres. Over a seven-year period, until 1894, the Théâtre Libre staged some 111 plays. His work had enormous influence on the French stage, as well as on similar companies elsewhere in Europe, such as the Independent Theatre Society in London and the Freie Buhne in Germany.
