The term countertransference was coined by Sigmund Freud in 1909 in his correspondence with Carl Gustav Jung. From 1908 to 1909, Jung had a sexual relationship with Sabina Spielrein, who had been his patient since 1904, initially due to a psychotic episode at the Burghölzli psychiatric university clinic in Zurich, and later in his private practice. Subsequently, he had further sexual relationships with his patients, such as Antonia Wolff (see Krutzenbichler & Essler, 2002). Both Sabina Spielrein and Jung’s wife, Emma Jung, turned to Freud to inform him about the love affair, to which he reacted with shock. He introduced the concept of countertransference, by which he meant all feelings and impulses triggered in the psychoanalyst by his patients. Thus, countertransference represented the opposite of Freud’s concept that the psychoanalyst should serve as a pure mirror for the patients, merely reflecting their experiences while remaining completely unemotional, i.e., abstinent, feeling nothing of his own, let alone showing it. For this reason, he should not believe that feelings of love from patients are actually directed at him, since these are feelings that are, in fact, related to their parents, such as their father. They are only transferred onto him because the patient, in the mirror, does not see the psychoanalyst as a person and a man, but rather sees her father. Freud (1915, p. 308) admonished his colleagues not to flatter themselves too much about a patient’s infatuation:
