About Thomas Main

Lived 1911 – 1990 (aged 79). Thomas Main was a British military physician and psychiatrist, known for British Journal of Medical Psychology and Cassel Hospital.

Thomas Forrest Main (1911–1990) was a South African-British psychiatrist and psychoanalyst who coined the term 'therapeutic community'. He is particularly remembered for his often cited paper, The Ailment.

Life Thomas Main was born on 25 February 1911 in Johannesburg, where his father was a mine manager who had emigrated there from England. At the start of World War I his mother returned to England with Thomas and his two sisters Isabella and Mary, while his father joined the South African Army. Main was educated at the Royal Grammar School, Newcastle-upon-Tyne before studying medicine at Durham University, graduating in 1933 and becoming a doctor in 1938. Specializing in psychiatry, he gained a Diploma in Psychological Medicine from Dublin in 1936. In 1937 he married Agnes Mary (Molly) McHaffie who also graduated in medicine at Durham University and who also became a psychoanalyst. They had three daughters and a son, Jennifer (Johns), Deborah (Hutchinson), Ursula (Kretzschmar) and Andrew.

Main worked as superintendent at Gateshead Mental Hospital. During the Second World War he joined the Royal Army Medical Corps as an adviser in psychiatry, attaining the rank of lieutenant colonel and working at the Northfield Army Hospital for the treatment of war neuroses. The work conducted at Northfield is considered by many psychiatrists to have been the first example of an intentional therapeutic community. The principles developed at Northfield were also developed and adapted at Civil Resettlement Units established at the end of the war to help returning prisoners of war to adapt back to civilian society and for civilians to adapt to having these men back amongst them.

The term "therapeutic community" was coined by Lt. Col. Main in his 1946 paper, "The hospital as a therapeutic institution", and subsequently developed by others including Maxwell Jones, R. D. Laing at the Philadelphia Association, David Cooper, and by Joshua Bierer.

After the war Main joined the Cassel Hospital, as medical director in 1946 and continued working there for the next thirty years.

Works The hospital as a therapeutic institution The Ailment and other Psycho-Analytical Essays, ed. Jennifer Johns, London: Free Association Books, 1989. . The noted essay, The Ailment, is a report of Main's detailed study of the feelings aroused in a team of nurses caring for a group of psychiatric patients with low potential for recovery. He found that a sedative would be used in the management of a patient "only at the moment when the nurse had reached the limit of her human resources and was no longer able to stand the patient's problems without anxiety, impatience, guilt, anger or despair".
