Stella Adler was one of the most important woman theater artists of the 20th Century. Born into a legendary Yiddish theater family and a founding member of the Group Theater, Adler was the only major American acting teacher to study with Konstantin Stanislavski. She based her technique on his renowned "System" approach to acting. Adler's work earned her a reputation as one of the most dynamic and disciplined actresses of her time, as well as a leading teacher and theorist. In 1949 she established the Stella Adler Studio of Acting in New York which, along with its sister school, the Art of Acting Studio in Los Angeles, continues to train actors in world-class programs.
