Sylvia Thalberg

She spent most of her early life in Brooklyn before joining her brother in Los Angeles in the late 1920s.

[2] With the release of 1930's Montana Moon, she and co-writer Frank Butler were noted as the only screenwriters at the time who had prepared the original story, adaptation, continuity and dialogue for a sound film.

[4] In 1933, she resigned her position at MGM aiming to spend her time writing novels.

At the time, she had tired of being accused of benefiting from her brother's position, and her novel, Too Beautiful, had been accepted for publication.

[5] She wasn't gone from the business long, however; later that year, she was signed to co-write a script at Paramount and later officially joined its staff.
