Enrique Pichon-Rivière

Enrique Pichon-Rivière (June 25, 1907 – July 16, 1977) was a Swiss-born Argentine psychiatrist, considered one of the introducers of group psychoanalysis in Argentina and generator of the group theory known as ''Grupo operativo'' (Operative Groups).

In the 1940s he became one of the founding members of the ''Asociación Argentina de Psicoanálisis'' (Argentine Psychoanalytic Association, or APA) and in the 1950s participated in the creation of the first private school of Social Psychology and the ''Instituto Argentino de Estudios Sociales'' (Argentine Institute of Social Studies, or IADES). The originality of his theory is based on the dialectical view of the functioning of the groups and the relationship between dialectic, homeostasis and cybernetic. Provided by Wikipedia
