An eyewitness account provides evidence of a significant clandestine effort to neutralize the legitimacy and authority of psychoanalysis. In a letter, the witness confirms the existence of a perfectly staged concerted action among German psychiatrists against Freud's influence in 1913. Their congress in Breslau was meant to present the united front of German psychiatrists, who were going on record as being against psychoanalysis and, in that context, to give Eugen Bleuler, a leading psychiatrist, whose (however half-hearted) support for psychoanalysis had alarmed his colleagues, a public opportunity for back-pedalling. The letter shows that Freud and his allies were not the only ones who tried to manage an intellectual movement by using informal networks and ‘behind the scenes’ manoeuvring.
