Step-by-step explanation:
In 1792, Philippe Pinel and his colleague were memorialized for their significant contributions to the field of psychiatry and mental health reform in France.
They were instrumental in advocating for humane treatment and improving conditions for mentally ill patients at the Bicêtre Hospital and the Salpêtrière Hospital in Paris.
Pinel is especially known for his influential work in introducing moral treatment and removing chains from patients, promoting the idea that mental illnesses should be treated with compassion, understanding, and therapy rather than punishment.
