Many of Stanislavski's former students taught acting in the United States, including Richard Boleslavsky, Maria Ouspenskaya, Michael Chekhov, Andrius Jilinsky, Leo Bulgakov, Varvara Bulgakov, Vera Solovyova, and Tamara Daykarhanova. Others—including Stella Adler and Joshua Logan—"grounded careers in brief periods of study" with him. Boleslavsky and Ouspenskaya went on to found the influential American Laboratory Theatre (1923—1933) in New York, which they modeled on the First Studio. Boleslavsky's manual "Acting: The First Six Lessons" (1933) played a significant role in the transmission of Stanislavski's ideas and practices to the West. In the Soviet Union, meanwhile, another of Stanislavski's students, Maria Knebel, sustained and developed his rehearsal process of "active analysis", despite its formal prohibition by the state.
