Learning from the past: inequalities and discrimination in psychiatry's chequered history.

The Royal College of Psychiatrists' antiquarian book collection originated from the library of psychiatrist Daniel Hack Tuke (1827-1895). A proposal to name the collection after him led us to investigate aspects of his life and work, particularly related to his attitudes concerning race, gender and homosexuality. We juxtaposed his ideas with those of some of his contemporaries. We cannot separate psychiatrists, past or present, from the societal and scientific context that shapes their professional understanding and standards. However, changes in language, knowledge, values and other sociocultural factors over time can affect how we perceive our forebears and how future generations of psychiatrists may perceive us.
