Short answers, pulled from the story.
Vivien Leigh won two Academy Awards for Best Actress. The first was for her performance as Scarlett O'Hara in Gone with the Wind (1939), and the second was for playing Blanche DuBois in the film version of A Streetcar Named Desire (1951).
Vivien Leigh suffered from two serious conditions throughout her life: chronic tuberculosis, first diagnosed in the mid-1940s in her left lung, and manic depression (bipolar disorder). Her tuberculosis ultimately caused her death on the 8th of July 1967, when her lungs filled with fluid. Her bipolar disorder led to several major breakdowns and contributed to periods when she was unable to work.
Vivien Leigh secured the role of Scarlett O'Hara after her American agent Myron Selznick, who was also David O. Selznick's brother, arranged an introduction on the set where the burning of Atlanta was being filmed. The following day, Leigh read a scene for Selznick, who organised a screen test with director George Cukor. Cukor praised Leigh's "incredible wildness" and she was cast shortly after.
Vivien Leigh was married twice. Her first husband was Herbert Leigh Holman, a barrister she married on the 20th of December 1932, with whom she had a daughter, Suzanne. Her second husband was actor and director Laurence Olivier, whom she married on the 31st of August 1940 and divorced in 1960. After the divorce, she was in a long-term relationship with actor John Merivale.
Vivien Leigh was born Vivian Mary Hartley on the 5th of November 1913 in Darjeeling, Bengal Presidency, in British India. She was the only child of Ernest Richard Hartley, a British broker born in Scotland, and his wife Gertrude, who was born in Darjeeling and was of possible Irish, Parsi Indian, and Armenian ancestry.
For her performance as Blanche DuBois in the 1951 film version of A Streetcar Named Desire, Vivien Leigh won the Academy Award for Best Actress, the BAFTA Award for Best British Actress, the New York Film Critics Circle Award for Best Actress, and the Volpi Cup for Best Actress at the Venice Film Festival. She had also played the same role on the London West End stage in 1949, after a run of 326 performances.
