Like every other superhero, Wonder Woman has a secret identity. Unlike every other superhero, she also has a secret history. Drawing from an astonishing trove of documents, including never-before-seen private papers, Harvard historian and New Yorker staff writer Jill Lepore reveals the fascinating family story that sparked the invention of the most popular female superhero of all time. Delving into the life of Wonder Woman's eccentric creator, psychologist William Moulton Marston, Lepore her feminist origins: from the warrior princesses of the Amazon, to suffragists including Emmeline Pankhurst, and the women Marston shared his life with - his wife and his mistress. The Secret History of Wonder Woman is at once a riveting work of pop culture history, and a crucial insight into the struggle for women's rights in the twentieth century and the troubled place of feminism today.
