Société Parisienne de Psychanalyse
Société Parisienne de Psychanalyse (SPP)
The SPP was a member body of the International Psycho-Analytical Association (IPA)
Lacan was a member of the SPP until 1953.
There was a disagreement about analytic practice methods.
Lacan (and many of his colleagues) left the SPP to form (a new group) the Société Française de Psychanalyse (SFP) ("French Psychoanalytic Society").
