Freud was an Austrian neurologist and the founder of psychoanalysis, who created an entirely new approach to the understanding of the human personality. He is regarded as one of the most influential - and controversial - minds of the 20th century. Sigismund (later changed to Sigmund) Freud was born on 6 May 1856 in Freiberg, Moravia (now Pribor in the Czech Republic). His father was a merchant. The family moved to Leipzig and then settled in Vienna, where Freud was educated. Freud's family were Jewish but he was himself non-practicing. In 1873, Freud began to study medicine at the University of Vienna. After graduating, he worked at the Vienna General Hospital. He collaborated with Josef Breuer in treating hysteria by the recall of painful experiences under hypnosis. In 1885, Freud went to Paris as a student of the neurologist Jean Charcot. On his return to Vienna the following year, Freud set up in private practice, specializing in nervous and brain disorders. The same year he married Martha Bernays, with whom he had six children.
