'''Sigmund Freud''' (1856–1939) was the founder of [[psychoanalysis]].
In 1938 he left fled Vienna and persecution by the [[Nazi]]s to North [[London]],[[England]], where he lived until his death in 1939.
Freud is best known for his theories of the [[unconscious mind]], especially involving the mechanism of [[repression]]; his symbolic interpretation of dreams; his redefinition of sexual desire as mobile and directed towards a wide variety of objects; and his therapeutic technique, especially his understanding of [[transference]] in the therapeutic relationship and the symbolic interpretation of dreams as sources of insight into [[unconscious desire]]s.
Freud proposed that the human [[psyche]] consists of three parts -- [[Ego]], [[super-ego]], and [[id]] -- and that [[defense mechanism]]s are an attempt by the mind to resolve conflicts between the super-ego and the id.
Some of Freud's revolutionary ideas have been shown to be correct.{{fact-science}} One of Freud's major contributions was the recognition of an [[unconscious]] mind being able to guide and control thoughts and behavior.{{fact-science}} Also Freud was the first to popularize the idea that people can go through [[developmental stage]]s in both mind and body. <ref>See also: Whyte, Lancelot Law: [http://www.amazon.com/Unconscious-Before-Freud-Lancelot-Whyte/dp/0312828705 ''The Unconscious Before Freud''] (Palgrave Macmillan, 1979)</ref>
Freud's theories are viewed by some as unscientific because they lack [[falsifiability]], as pointed out by [[Karl Popper]}.<ref>Popper, Karl R.: [http://www.stephenjaygould.org/ctrl/popper_falsification.html 'Science as Falsification'], ''Conjectures and Refutations: The Growth of Scientific Knowledge'' (London, 1963) </ref>
Much of Freud's psychosexual theories and his tripartite model have failed any empirical investigation. Psychoanalysis as a [[clinical psychology | clinical]] method has in many cases been shown to be as effective as other talk therapies,{{fact-science}}
but this is not likely to reflect the accuracy or inaccuracy of the underlying theories, but rather the positive effect of talking about one's problems.
Sigmund Freud died of maxillary [[cancer]] at the age of 82.
