Abstract

Philippe Pinel (1745–1826) is often said to be the father of modern clinical psychiatry. He is most famous for being a committed pioneer and advocate of humanitarian methods in the treatment of the mentally ill, and for the development of a mode of psychological therapy known as moral treatment. Pinel also made important contributions to nosology and the diagnosis and treatment of mental disorder, especially the psychopathology of affectivity, stressing the role of the passions in mental disorder. Pinel also conducted what may be considered one of the first large‐scale clinical trials in psychiatry and was also arguably the first to introduce the new statistical methods of the time to that domain.
