existing theory, Freud gives detailed interpretations of his own and his patients' dreams in terms of wish-fulfillments made subject to the repression and censorship of the "dream-work". He then sets out the theoretical model of mental structure (the unconscious, pre-conscious and conscious) on which this account is based. An abridged version, On Dreams, was published in 1901. In works that would win him a more general readership, Freud applied his theories outside the clinical setting in The Psychopathology of Everyday Life (1901) and Jokes and their Relation to the Unconscious (1905). In Three Essays on the Theory of Sexuality, published in 1905, Freud elaborates his theory of infantile sexuality, describing its "polymorphous perverse" forms and the functioning of the "drives", to which it gives rise, in the formation of sexual identity. The same year he published Fragment of an Analysis of a Case of Hysteria, which became one of his more famous and controversial case studies. Known as the 'Dora' case study, for Freud it was illustrative of hysteria as a symptom and contributed to his understanding of the importance of transference as a clinical phenomena. In other of his early case studies Freud set out to describe the symptomatology of obsessional neurosis in the case of the Rat man, and phobia in the case of Little Hans. Transference is the process by which patients displace onto their analyst feelings and ideas which derive from previous figures in their lives. Transference was first seen as a regrettable phenomenon that interfered with the recovery of repressed memories and disturbed patients' objectivity, but by 1912, Freud had come to see it as an essential part of the therapeutic process. Early followers In 1902, Freud, at last, realised his long-standing ambition to be made a university professor. The title "professor extraordinarius" was important to Freud for the recognition and prestige it conferred, there being no salary or teaching duties attached to the post (he would be granted the enhanced status of "professor ordinarius" in 1920). Despite support from the university, his appointment had been blocked in successive years by the political authorities and it was secured only with the intervention of one of his more influential ex-patients, a Baroness Marie Ferstel, who (supposedly) had to bribe the minister of education with a valuable painting. With his prestige thus enhanced, Freud continued with the regular series of lectures on his work which, since the
