Philippe Pinel

Philippe Pinel (French: [pinɛl]; 20 April 1745 – 25 October 1826) was a French physician, precursor of psychiatry and incidentally a zoologist. He was instrumental in the development of a more humane psychological approach to the custody and care of psychiatric patients, referred to today as moral therapy. He worked for the abolition of the shackling of mental patients by chains and, more generally, for the humanisation of their treatment. He also made notable contributions to the classification of mental disorders and has been described by some as "the father of modern psychiatry".

After the French Revolution, Dr. Pinel changed the way we look at the mentally ill (or "aliénés", "alienated" in English) by claiming that they can be understood and cured. An 1809 description of a case that Pinel recorded in the second edition of his textbook on insanity is regarded by some as the earliest evidence for the existence of the form of mental disorder later known as dementia praecox or schizophrenia, although Emil Kraepelin is generally accredited with its first conceptualisation.

"Father of modern psychiatry", he was credited with the first classification of mental illnesses. He had a great influence on psychiatry and the treatment of the alienated in Europe and the United States.
