Nellie Bly
Nellie Bly was an investigative journalist who took her job incredibly seriously. So seriously, in fact, that she herself went undercover as a patient in an insane asylum in n attempt to expose the many abusive practices taking place there. This was way back in 1887, by the way. As if that wasn’t kick @$$ enough, a year later she also managed to travel around the entire globe in 72 days.
