Viewing the reception of psychoanalysis in Britain from Cambridge, the paper examines the intertwining histories of the post-War British Psychological Society and the founding of the British Psycho-Analytical Society, following the initiatives of the two principal psychological entrepreneurs of the era, Charles Myers and Ernest Jones. Reforms in Cambridge in which psychoanalysis played a significant part are analysed, including the foundation of a Clinic for Nervous Diseases and the establishment of a separate Department of Experimental Psychology. The career of J.T. MacCurdy, Jones's student and Lecturer in Psychopathology at Cambridge, is discussed.
