Sigmund Freud (May 6, 1856-September 23, 1939) was an Austrian neurologist and the founder of the psychoanalytic school of psychology. The theories distinctive of this school generally included the following hypotheses: (1) that human development is best understood in terms of changing objects of sexual desire, (2) that the psychic apparatus habitually represses wishes, usually of a sexual or aggressive nature, whereby they become preserved in one or more unconscious systems of ideas, (3) that unconscious conflicts over repressed wishes have a tendency to manifest themselves in dreams, parapraxes ("Freudian slips"), and symptoms, (4) that unconscious conflicts are the source of neuroses, and (5) that neuroses can be treated through bringing the unconscious wishes and repressed memories to consciousness in psychoanalytic treatment.
The name Freud is generally pronounced /fɹɔɪd/ in English and /frɔɪt/ in German. He is commonly referred to as "the father of psychoanalysis" and may also be regarded as the father of modern Psychology.
