Toni Merlin Ratner
Joanna Merlin (born July 15, 1931) is an American actress and casting director who has worked with Stephen Sondheim and starred in the original Broadway production of Fiddler on the Roof. She has written two acting guides and is a faculty member of New York University's graduate acting program. In recent years, she has become known for her recurring role on Law & Order: Special Victims Unit as Judge Lena Petrovsky.
Early life 
Joann Ratner, who later took her mother's maiden name, was born in Chicago, Illinois to Toni Merlin and Harry Ratner, who worked as a grocer. She first acted on stage at age 11, joining a community theatre production, Too Many Marys. Merlin graduated from UCLA and later studied under Michael Chekhov, learning his world renowned acting technique. She has been described as the last student of Michael Chekhov who is still alive and teaching.
Merlin made her first screen appearance in Cecil B. DeMille's film The Ten Commandments in 1956. Five years later, she made her Broadway debut in Becket before playing Tzeitel in Harold Prince's production of Fiddler on the Roof. She left the cast of Fiddler on the Roof before the end of its tour to take care of her two small children but Harold Prince gave her the opportunity to become involved in casting with a more flexible schedule. Company was the first musical for which Merlin served as the casting director. She was also in charge of casting for such plays as Follies, Evita and Sweeney Todd. After making appearances in several feature films, Merlin appeared in the NBC crime drama Law & Order in 1992 as a defense attorney. Like many actors from that show, she went on to play other characters in the Law & Order franchise - another defense attorney in the original show and Judge Lena Petrovsky in its first spin-off Law & Order: Special Victims Unit. In the latter role, she appeared in every season between the years 2000 and 2011.
In 2001, Joanna Merlin wrote Auditioning: An Actor-Friendly Guide and in 2007, shared her knowledge of the theatre industry in the instructional video Master Classes in the Michael Chekhov Technique. She teaches in New York University's graduate acting program at the Tisch School of the Arts and in 1999, founded the Michael Chekhov Association where she teaches acting workshops.
