During the Second World War, it is argued, “the neuroses of battle” not only deepened an understanding of “psychopathological mechanisms”, but also created opportunities for the practice of psychotherapy, while its perceived efficacy led to a broader acceptance within medicine and society once peace had returned. This recognition is contrasted with the aftermath of the First World War when a network of outpatient clinics, set up by the Ministry of Pensions to treat veterans with shell shock, were closed within a few years in response to financial pressures and doubts about their therapeutic value. In the private sector, psychoanalysis under the leadership of Ernest Jones remained an idiosyncratic activity confined largely to the affluent middle classes of London. According to Gregorio Kohon, “it was strongly opposed by the general public, the Church, the medical and psychiatric establishment, and the press”. The Medico-Psychological Clinic of London, originally set up in 1913, offered psychotherapy on three afternoons a week in premises at 30 Brunswick Square under the direction of Dr James Glover. However, it closed in 1923 after Glover and his brother Edward had both become psychoanalysts. As the First World War drew to a close, Maurice Craig helped to persuade Sir Ernest Cassel to fund a hospital for ‘Functional and Nervous Disorders’ at Penshurst, Kent, to treat neuroses in the civilian population. Although moved to permanent premises near Richmond, it remained small-scale and at the time no attempt was made to establish a network of similar institutions throughout the UK. The Tavistock Clinic, opened in Bloomsbury in 1920, struggled to secure funding throughout the interwar period and its efforts to win official recognition from the University of London were consistently rebutted. Thus, despite the epidemic of shell shock and other so-called war neuroses, psychotherapy remained a marginal activity during the 1920s and 1930s.
