Sigmund Freud explored the connections between mother-fixation and a long series of love-attachments in the first of his articles on the 'Psychology of Love';[5] while Otto Rank published an article on the Don Juan gestalt in 1922.[6] Otto Fenichel saw Don Juanism as linked to the quest for narcissistic supply, and for proof of achievement (as seen in the number of conquests).[7] He also described what he called the 'Don Juans of Achievement' – people compelled to flee from one achievement to another in an unconscious but never ending quest to overcome an unconscious sense of guilt[8] Sándor Ferenczi stressed the fear of punishment (Hell) in the syndrome, linking it to the Oedipus complex.[9]
