Answer:
Dorothea Dix.
Step-by-step explanation:
Dorothea Dix's main idea was to develop a humane psychological treatment for the individual, for anyone regardless of their lifestyle.
Moral therapy began to develop as a natural and respectful treatment for patients, centering on the moral and humane treatment for the mentally ill.
Dix began to develop the mental hygiene movement after attending a jail in Massachusetts in which she was witness to the deplorable conditions the patients faced, thus becoming a crusader for a humane treatment.
