Sigmund Freud was born in 1856 in Moravia, which was then part of the Austrian Empire and is now in the Czech Republic. He spent most of his life in Vienna, from where he fled, in 1937, when the Nazis invaded. Neither Freud (being Jewish) or his theories were very popular with the Nazis and he escaped to London where he died in 1939.

He had wanted to be a research scientist but anti-Semitism forced him to choose a medical career instead and he worked in Vienna as a doctor, specialising in neurological disorders (disorders of the nervous system). He constantly revised and modified his theories right up until his death but much of his psychoanalytic theory was produced between 1900 and 1930.

Freud originally attempted to explain the workings of the mind in terms of physiology and neurology ...(but)... quite early on in his treatment of patients with neurological disorders, Freud realised that symptoms which had no organic or bodily basis could imitate the real thing and that they were as real for the patient as if they had been neurologically caused. So he began to search for psychological explanations of these symptoms and ways of treating them.

In 1885 he spent a year in Paris learning hypnosis from the neurologist Charcot; he then started using hypnosis with his patients in Vienna. However, he found its effects to be only temporary at best and it did not usually get to the root of the problem; nor was everybody capable of being hypnotised. Meanwhile Breuer, another Viennese doctor, was developing another method of therapy which he called the cathartic method, where patients would talk out their problems. Freud adopted Breuer’s method and called it free association which became one of the three fundamental tools of psychoanalysis.

Freud began his self-analysis during the 1890s and in 1900 published The Interpretation of Dreams, in which he outlined
