Freud suggested to Fliess in 1897 that addictions, including that to tobacco, were substitutes for masturbation, "the one great habit."
Fliess's surgery proved disastrous, resulting in profuse, recurrent nasal bleeding - he had left a half-meter of gauze in Eckstein's nasal cavity the subsequent removal of which left her permanently disfigured.
The departure from Vienna began in stages throughout April and May 1938.
