This article discusses the early theoretical works of the Hungarian psychoanalyst and a close disciple of Sigmund Freud, Sándor Ferenczi. This study offers an interpretation of his short case study Homosexualitas Feminina, published in 1902, concentrating on the analyst’s narrative and stylistic strategies before he met the founder of psychoanalysis. The article is devoted to the analysis of a popular medical genre – the case study – which is seen in the light of its relation to life-writing literature. Rather than follow Michel Foucault’s deconstructive scheme of interpretation, I offer a more affirmative reading of the case study of Rosa K. and thus seek to understand Ferenczi’s early work through the impact of life-writing genres, such as biography and autobiography, on psychiatric discourse at the turn of the twentieth century.
