In the United States, one of Boleslavsky's students, Lee Strasberg, went on to co-found the Group Theatre (1931—1940) in New York with Harold Clurman and Cheryl Crawford. Together with Stella Adler and Sanford Meisner, Strasberg developed the earliest of Stanislavski's techniques into what came to be known as "Method acting" (or, with Strasberg, more usually simply "the Method"), which he taught at the Actors Studio. Boleslavsky thought that Strasberg over-emphasised the role of Stanislavski's technique of "emotion memory" at the expense of dramatic action.
