Sadism and Masochism - The Psychology of Hatred and Cruelty - Vol. II. (Electronic book text)

Wilhelm Stekel was an Austrian physician and psychologist, who became one of Sigmund Freud's earliest followers, and was once described as "Freud's most distinguished pupil." According to Ernest Jones, "Stekel may be accorded the honour, together with Freud, of having founded the first psycho-analytic society"; while he also described him as "a naturally gifted psychologist with an unusual flair for detecting repressed material."
