Stanislavski eventually came to organise his techniques into a coherent, systematic methodology, which built on three major strands of influence: (1) the director-centred, unified aesthetic and disciplined, ensemble approach of the Meiningen company; (2) the actor-centred realism of the Maly; and (3) the Naturalistic staging of Antoine and the independent theatre movement. Stanislavski's earliest reference to his system appears in 1909, the same year that he first incorporated it into his rehearsal process. Olga Knipper and many of the other MAT actors in that production—Ivan Turgenev's comedy "A Month in the Country"—resented Stanislavski's use of it as a laboratory in which to conduct his experiments. At Stanislavski's instistence, the MAT went on to adopt his system as its official rehearsal method in 1911.
