Philippe Pinel (April 20, 1745 – October 25, 1826) is a French physician who is 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 also makes notable contributions to the classification of mental disorders and has been described by some as "the father of modern psychiatry".
An 1809 description of a case that Pinel records in the second edition of his textbook on insanity is regarded as the earliest evidence for the existence of the form of mental disorder known as dementia praecox or schizophrenia in the twentieth century by some, although Emil Kraepelin is generally accredited with its first conceptualization.
