William Tuke (24 March 1732 – 6 December 1822), an English tradesman, philanthropist and Quaker, earned fame for promoting more humane custody and care for people with mental disorders, using what he called gentler methods that came to be known as moral treatment. He played a big part in founding The Retreat at Lamel Hill, York, for treating mental-health needs. He and his wife Esther Maud backed strict adherence to Quaker principles. He was an abolitionist, a patron of the Bible Society, and an opponent of the East India Company's inhumane practices.
