Sigmund Freud (6 May 1856 23 September 1939), born Sigismund Schlomo Freud, was an Austrian neurologist who became known as the founding father of psychoanalysis. Freud's parents were poor, but they ensured his education. Freud chose medicine as a career and qualified as a doctor at the University of Vienna, subsequently undertaking research into cerebral palsy, aphasia and microscopic neuroanatomy at the Vienna General Hospital. This led in turn to the award of a University lectureship in neuropathology, a post he resigned once he had decided to go into private practice. On the basis of his clinical practice Freud went on to develop theories about the unconscious mind and the mechanism of repression, and created psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient (or 'analysand') and a psychoanalyst.
