Sigmund Freud

Sigmund Freud (6 May 1856 – 23 September 1939), was a Jewish Austrian neurologist who founded the psychoanalytic school of psychiatry. Freud is best known for his theories of the unconscious mind and the defense mechanism of repression, and for creating the clinical practice of psychoanalysis for treating psychopathology through dialogue between a patient, technically referred to as an "analysand", and a psychoanalyst. Freud is also renowned for his redefinition of sexual desire as the primary motivational energy of human life
