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.[4] They had three daughters and a son, Jennifer (Johns),[5] Deborah (Hutchinson), Ursula (Kretzschmar) and Andrew.
The term "therapeutic community" was coined by Lt. Col. Main in his 1946 paper, "The hospital as a therapeutic institution",[8][9] 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.[4]
The Ailment and other Psycho-Analytical Essays, ed. Jennifer Johns, London: Free Association Books, 1989. ISBN1-85343-105-2. 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".
