Eliot Slater's first marriage was dissolved in 1946 and he married Jean Fyfe Foster in the same year. Also in 1946, he was appointed Physician in psychological medicine at the National Hospital for Nervous Diseases, Queen Square, London, where he worked for eighteen years. He resigned in 1964 in protest at the hospital's rejection of the offer of a benefaction from the
Mental Health Research Fund to establish a chair in psychiatry, Among his numerous other publications, one to be singled out is
Clinical Psychiatry (with Willi Mayer-Gross and
Martin Roth, 1954), which became a standard textbook for doctors and students, and remained so for many years (third edition 1969 by Slater and Roth; revised 1977). He gave the Litchfield (1959), Galton (1960) and Mapother (1960) lectures. In his Maudsley (1961) lecture and later writings he questioned the concept of 'hysteria' as a valid diagnosis, showing that serious physical illness subsequently emerged in many patients initially labelled 'hysterical' and arguing that the physical illness could often account for their allegedly psychological symptoms; They long advocated for a range of other 'physical' treatments, including
insulin coma therapy, even well after clinical trials cast doubt on its efficacy. It has been noted that originally (1944) they wrote that their judgements of efficacy – in the absence of any known theoretical basis for it – were on purely
empirical (research) grounds, but later (e.g. 1963) they justified them as the insights of the careful and attentive observer. They repeatedly emphasised benefits over psychotherapy in terms of speed and 'convenience' in dealing with large numbers of mental patients, and in 'certainty' of improvements; however the claims of curative or transformative powers proved hollow, and they were sometimes used to make patients easier to manage. Slater died at his home in Barnes, London, on 15 May 1983, being survived by his first and second wives and by the four children of his first marriage – a mathematician, a haematologist, a psychiatrist and an English don. == Outside interests ==
