ABSTRACT
Sandor Ferenczi would play an important role as a theoretician, as the founder of the Psychoanalytic Association in Budapest, and as the cofounder, with Sigmund Freud, of the International Psychoanalytical Association in 1910. In his book Thalassa, in which his perspective is close to that of Otto Rank, he placed the focus of his research on the archaic link between mother and child. Otto Rank, born in Vienna in 1884, was one of the first to meet Freud, as early as 1905. When Freud became interested in the phenomena of telepathy and thought transference, Jones considered that research on these subjects could compromise the scientific character of psychoanalysis. In 1949, Ernest Jones began to write the first major biography of Freud, thanks to his access to over 5,000 letters of Freud's private correspondence. The first volume of this impressive work in three volumes came out in 1953.
