Nellie Bly 
Ten Days in a Mad-House [EPUB ebook] 

Pen name of American pioneer female journalist Elizabeth Jane Cochran. She remains notable for two feats: a record-breaking trip around the world in emulation of Jules Verne’s character Phileas Fogg, and an exposé in which she faked insanity to study a mental institution from within. In addition to her writing, she was also an industrialist and charity worker.
