Rose Hobart, actress who began her Hollywood film career in 1930 and was subsequently blacklisted two decades later during the House Un-American Activities Committeehearings, died Aug. 29 at the Motion Picture & Television Hospital in Woodland Hills, Calif. She was 94.

Born in New York City, she was the daughter of musician Paul Kefer. She performed on the Broadway stage during the 1920s, toured with Noel Coward in “The Vortex” and played opposite Helen Hayes in “What Every Woman Knows.”

She came to Hollywood in 1930 and made her screen debut in the feature “Liliom” for Fox. She was subsequently signed by Universal and played leads in “A Lady Surrenders,” “East of Borneo” and “Scandal for Sale.”

During the early 1930s she appeared on the stage in “I Loved You Wednesday,” “Girls in Uniform,” “Springtime for Henry” and “The Wind and the Rain.” Hobart’s last major stage appearance was in “Dear Octopus” in 1939.

She returned to Hollywood that same year and played second leads in nearly two dozen films, including “Ziegfeld Girl,” “The Farmer’s Daughter” and “Bride of Vengeance.”

As a board member of the Actors Lab, she was called to testify before HUAC. She was unable to find work until the late 1950s, when she appeared on “The Danny Thomas Show.” She later became a semiregular on “Peyton Place.”

She is survived by a son, Judson Bosworth.
