Freud gave her the name 'Dora', and he describes in detail in The Psychopathology of Everyday Life what his unconscious motivations for choosing such a name might have been. His sister's nursemaid had to give up her real name, Rosa, when she accepted the job because Freud's sister was also named Rosa—she took the name 'Dora' instead. Thus, when Freud needed a name for someone who could not keep her real name (this time, in order to preserve his patient's anonymity), Dora was the name that occurred to him.[16]
