Nellie Bly, the Heroine Nobody Hears About
Elizabeth Jane Cochran, actually. Nellie Bly was her pseudonym. She landed her first newspaper job by writing a furious letter to the editor, words leaping off the page to slap a misogynist columnist. This was in 1885. Then she moved to New York and spent four penniless months persuading Joseph Pulitzer to hire her at the New York World.
