 An annual S. H. Foulkes lecture for a wider public has been held in London since 1977; the lectures are published in the journal Group Analysis.After the Second World War, and after the experiments in treating soldiers by group methods at Northfield Hospital near Birmingham, a circle of colleagues interested in furthering their understanding of groups and how to apply group psychotherapy met regularly with Foulkes.In 1971, leading members of the Society set up the Institute of Group Analysis, which became responsible for training, including an intensive qualifying course that leads to membership of the Institute.
