Sigmund Freud
Sigmund Freud (born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies arising from conflicts in the psyche through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it. In creating psychoanalysis, Freud introduced therapeutic methods such as free association, the interpretation of dreams, and the analysis of transference phenomena that arise in the clinical setting.
