Wonder Woman, created in 1941, is the most popular female superhero of all time. Her creator, William Moulton Marston, was influenced by early suffragists and feminists, starting with Emmeline Pankhurst, who was banned from speaking on Harvard's campus in 1911, when Marston was a freshman. Marston and his wife bought their home from Olive Byrne, the niece of Margaret Sanger, one of the most influential feminists of the twentieth century, and they lived a life of extraordinary nonconformity. Harvard historian and New Yorker staff writer Jill Lepore has uncovered an astonishing trove of documents, including the never-before-seen private papers of William Moulton Marston, for her new book The Secret History of Wonder Woman.
