Uta Hagen

She later became a highly influential acting teacher at New York's Herbert Berghof Studio and authored best-selling acting texts, ''Respect for Acting'', with Haskel Frankel, and ''A Challenge for the Actor''. Her most substantial contributions to theatre pedagogy were a series of "object exercises" that built on the work of Konstantin Stanislavski and Yevgeny Vakhtangov.
She was elected to the American Theater Hall of Fame in 1981. She twice won the Tony Award for Best Actress in a Play and received a Special Tony Award for Lifetime Achievement in 1999. Provided by Wikipedia
