Tall (5' 9"), blonde-haired US stage, screen and TV actress from the 1930's through the mid-1960's. Upon retiring from acting Jean went on to teach drama, first, for eight years beginning in 1968, at Stephens College in Columbia, Missouri, where she headed their new drama department, and afterwards at a university in Mexico.
In 1950 she was blacklisted by the television industry as a suspected Communist.
Was the original choice for 埃罗尔·弗林's leading lady in the classic swashbuckler Captain Blood (1935) but the role ultimately went to young 18-year-old 奥利维娅·德哈维兰, who impressed critics and audiences in the film 仲夏夜之梦 (1935), which also co-starred Ms. Muir.
In the 30s as a Warner Bros.' contract player, she was nicknamed "The Studio Pest" because she always had questions about everything from camera angles to publicity practices.
Disappointed at never being given a strong movie part, she quit films in 1943 and moved to radio, TV and stage work.
Her name appeared in "Red Channels" the "anti-Communist" pamphlet and her career was irreparably damaged. This led to a bout with alcoholism, which she recovered from.
In later years she taught drama in community playhouses and summer drama schools.
Her ex-husband, Henry Jaffe, was a New York City attorney.
