Edoardo Weiss

Weiss's first article, on the psychodynamics of asthma attacks, was published in 1922, and was followed over the next two decades by seven more, on subjects ranging from acting out to the fear of blushing.

Weiss introduced the concept of destrudo into psychoanalysis,[3] as well as that of psychic presence: the mental awareness of the internalised image of another ego, often parental, in oneself.

[4] From this and other studies in ego states stemmed his major influence on such later figures as Eric Berne and John G.

[5] Weiss's interest in psychoanalysis led to him visiting the Vienna Psychoanalytic Society in 1908;[6] he would subsequently be analysed by a leading member of that group, Paul Federn, with whom he established a lifelong collaboration.

[7] After the Anschluss of 1938, Weiss emigrated to America, to work first at the Menninger Clinic,[8] and then with Franz Alexander in Chicago.
