A new biography, Ideal Beauty: The Life and Times of Greta GarboI, by feminist historian Lois Banner—who’s the cofounder of the Berkshire Conference of Women Historians—presents Greta Louisa Gustafson (1905–1990) as Dr. Jekyll and Ms. Hyde. So much has been written about the actress that the Hollywood dream factory exploited as a marketable commodity during the 1920s and ’30s, when Garbo was billed as “the most beautiful woman in the world,” that it’s a challenge to say something new. Banner’s book offers a feminist rehash of Garbo’s childhood and reprises the well-known struggles on her quest for cinematic fame and financial freedom.
