Diane Roter

Her native language is French. Her family, Holocaust survivors of Jewish descent, immigrated from postwar Europe to the United States. She learned English as a child. Her family is closely associated with theater and acting, so they settled in California close to Hollywood. Her family founded the Santa Monica Playhouse in the early 1960s. She sharpened her innate talent in acting with the Stanislavsky method as a youth. Her first appearance on television was at age 10 on the General Electric Theater in 1959. She appeared with Charles Laughton. She later appeared on the Dick Powell Show in 1962. She appeared on this show with her brother, Robert. Her first stage performance was in William Saroyan's My Heart's in The Highlands at age 10. She won critical acclaim for her performance as the Student in Eugène Ionesco’s The Lesson at age 14. From the early '60s until her casting on The Virginian in 1965, she worked to improve her acting skills through the theater.

On The Virginian, she played the character of Jennifer Sommers, Judge Henry Garth's (Lee J. Cobb) niece. She joined the show taking the place of Betsy Garth (Roberta Shore), who left the show in the previous season. Her time in the TV series was cut short when Lee J. Cobb left the series before his contract was completed in the middle of the fourth season. Jennifer Sommers' character was independent, confident, and sharing, and she helped others in her day-to-day activities. She was left "home alone" many times as Judge Garth made business trips preparing to become the new Wyoming Territory governor. Other cast members of The Virginian with whom she appeared were James Drury, Doug McClure, Clu Gulager, and Randy Boone.

After her appearances in television, she trained with Marcel Marceau in Paris and performed as a mime at the Mark Taper Forum. She has taught mime and movement, as well as acting and writing, in private classes and in schools. She taught algebra to adults at Los Angeles Valley College and earned a bachelor of arts in biopsychology from UCLA, and was honored with a research training award. She has been published in journalism and art criticism in the Los Angeles Times, San Jose Mercury News, The Daily News, LA Weekly, and The Advocate.
