I hope this helps. Thanks for asking.

Dorthea Dix was given a lot of credit in the early 1800's.

Yes, you are correct. Philippe Pinel is often credited as one of the key figures responsible for the humanitarian movement to improve the conditions of insane asylums. He was a French physician who advocated for treating mental illness with compassion and kindness. In the late 18th century, Pinel implemented reforms in Paris where he removed the chains and restraints from the mentally ill patients, and focused on providing them with humane treatment and care.

Additionally, as you mentioned, Dorothea Dix was another important figure in the movement to improve conditions in asylums. She was an American activist, teacher, and writer who worked tirelessly in the early 19th century to expose the inhumane treatment of mentally ill individuals in the United States. Dix advocated for the establishment of state-funded mental hospitals and successfully lobbied for legislation to improve the conditions in asylums.
