A New England teacher and author who spoke against the inhumane treatment of insane prisoners, ca. 1830's. People who suffered from insanity were treated worse than normal criminals. Dorothea Dix traveled over 60,000 miles in 8 years gathering information for her reports, reports that brought about changes in treatment, and also the concept that insanity was a disease of the mind, not a willfully perverse act by an individual.
