Events mark Freud 150th birthday
Celebrations are being held to mark the 150th birthday of Sigmund Freud, seen as the father of psychoanalysis.
Events are being staged in Vienna - where Freud spent most of his life - and in London, where he was forced to flee from the Nazis in 1938.
But the Viennese celebrations are said to be muted compared to those planned for Mozart's 250th anniversary.
Freud is credited with developing theories mapping the human mind and its links to the unconscious.
His theories are said to have influenced the fields of art, literature, anthropology and religion.
