The Origins of the Notion of Countertransference.

The aim of this paper is to historically contextualize and analyze the birth and early development of the concept of countertransference, introduced by Sigmund Freud in 1909. In order to do so, scientific publications will be considered, as well as the epistolary and the historical information about the personal relationship between Freud and his students, and among his students and some of their colleagues and patients.
