Benedetti argues that a significant influence on the development of Stanislavski's system came from his experience teaching and directing at his Opera Studio. He created it in 1918 under the auspices of the Bolshoi Theatre, though it later severed its connection with the theatre. Stanislavski worked with his Opera Studio in the two rehearsal rooms of his house on Carriage Row (prior to his eviction in March 1921). His brother and sister, Vladimir and Zinaïda, ran the studio and also taught there. It accepted young members of the Bolshoi and students from the Moscow Conservatory. Stanislavski also invited Serge Wolkonsky to teach diction and Lev Pospekhin (from the Bolshoi Ballet) to teach expressive movement and dance.
