Gerard Chrzanowski was a prominent representative of psychoanalysis. However, he was not a friend of strict delimitations between the different psychoanalytic schools and the struggles between them. Having grown up in Poland, having lived a few years in Switzerland and the rest of his life in USA he had a multi-cultural background. He was with that well prepared to exert an integrative role between the different psychoanalytic movements and especially in the International Federation of Psychoanalysis, of which he was one of the founders and honourable members.
