Sorry there is no Biography!
Best remembered as Lina Lamont, the silent-film star in Singin' in the Rain, who could not manage the transition to talkies. (Not without Debbie Reynolds's help, that is.) In Singin' in the Rain, Debbie Reynolds lip synched to Jean's singing and spoken voice for "The Dancing Cavalier". In other words, Jean voiced-over the character who was supposed to be voicing over *her* character. A prolonged illness necessitated her early retirement in the mid-60s, entering a convalescent home for the rest of her life. A desire to act one more time happened for her in 1977 when she appeared briefly as a landlady in the TV-movie Alexander: The Other Side of Dawn. She died shortly after of throat cancer. Jean seemed a shoo-in to win the Best Supporting Actress Academy Award for her hilarious performance as Lina Lamont in Singin' in the Rain, but was beaten out for the award by Gloria Grahame for The Bad and the Beautiful. Though nominated twice for Emmy awards as Danny Thomas' first TV wife on his popular comedy series The Danny Thomas Show, Jean became disenchanted with the rather colorless mom role and left the series after four seasons. Marjorie Lord replaced her as Danny's perky second wife.
