Stanislavski's system is a progression of techniques used to train actors and actresses to draw believable emotions to their performances. The method that was originally created and used by Constantin Stanislavski from 1911 to 1916 was based on the concept of emotional memory for which an actor focuses internally to portray a character's emotions onstage. Later, between 1934 and 1938, this technique evolved to a method of physical actions in which emotions are produced through the use of these actions.The latter technique is referred to as Stanislavski's system. This approach was developed by Constantin Stanislavski (1863–1938), a Russian actor, director, and theatre administrator at the Moscow Art Theatre (founded 1897). The system is the result of Stanislavski's many years of efforts to determine how someone can control in performance the most intangible and uncontrollable aspects of human behavior, such as emotions and art inspiration. The most influential acting teachers, including Richard Boleslavsky, Vsevolod Meyerhold, Michael Chekhov, Lee Strasberg, Stella Adler, Harold Clurman, Robert Lewis, Sanford Meisner, Uta Hagen, Ion Cojar, Andrey Vasilyev, Ivana Chubbuck and Christine Anketell all traced their pedigrees to Stanislavski, his theories and/or his disciples.
