In America, the transmission of the earliest phase of Stanislavski's work via the students of the First Studio of the Moscow Art Theatre (MAT) revolutionized acting in the West. When the MAT toured the US in the early 1920s, Richard Boleslawski, one of Stanislavski's students from the First Studio, presented a series of lectures on the "system" that were eventually published as "Acting: The First Six Lessons" (1933). The interest generated led to a decision by Boleslawski and Maria Ouspenskaya (another student at the First Studio) to emigrate to the US and to establish the American Laboratory Theatre.
