was an active member of the British Eugenics Society. Encouraged by Aubrey Lewis, he had won a Rockefeller fellowship in 1934 to Germany, where he studied under Bruno Schulz and Ernst Rüdin at the Psychiatric Research Institute in Munich. Rüdin spearheaded the Nazis’ Rassenhygiene, a programme designed to encourage a ‘pure’ and ‘healthy’ Aryan race by avoiding miscegenation and procreation among mentally ill people. Enforced sterilisation, for example, had been introduced in 1933 to prevent interbreeding between the ‘feeble-minded’ and schizophrenics.
