Chertok's paper deals extensively with Freud's lecture, On Male Hysteria, presented in 1886 after Freud's return to Vienna following his studies with Charcot. The author's intent is to show how similar data can be seen in diverse ways by different authors. In this case, the central issue (in his view of the data versus that of Ellenberger) is the effect of Freud's work with Charcot on the subsequent development of psychoanalysis. His point is that years after the events in question, there is still sufficient emotional charge to bias the historian's view. What is of particular interest in this paper is its contribution in adding to the setting that existed at 'the dawn of dynamic psychology'.
