[1] Perrier was called by Élisabeth Roudinesco "the wandering troubadour of Lacanianism, naive and passionate, as whimsical as his master (whose genius he lacked), but a prodigious theorist of female sexuality, hysteria, and love".
[4] After the failure of their efforts, it was at Perrier's house, in the presence of Jacques Lacan and Nathalie Zaltzman, his ex-wife, that the founding of the Ecole Freudienne de Paris took place in 1964.
Perrier was the first to resign from the board of the new institution, in 1966, over the question of training; and in 1969, in what has been called the third schism in French psychoanalytic history, he, along with Piera Aulagnier, Jean-Paul Valabrega, and (a minority of) others broke away from the EFP to set up a fourth group: the Organisation psychanalytique de langue francaise (OPFL).
[7] Roudinesco highlighted for critical attention a letter he wrote to Lacan in 1965, shortly after the EFP was formed:[8] You are in the process of destroying what you claim to found, whether it be a school or a treaty of trust with your friends... bringing out the fact that your own relationship to any collegiate body is that of a loner, one who excludes himself voluntarily and rejects all groups...
[8] Perrier produced a large body of work, ranging from phobia (1956), psychosis (1956 and after), and erotomania (1966), to alcoholism and female sexuality, while also contributing to the question of the training analysis (1969).
