Sigmund Freud (IPA: [ born Sigismund Schlomo Freud (May 6, 1856 – September 23, 1939), was an Austrian neurologist and psychiatrist who founded the psychoanalytic school of psychology. Freud is best known for his theories of the unconscious mind and the defense mechanism of repression and for creating the clinical practice of psychoanalysis for curing psychopathology through a particular form of dialogue between a patient and a psychoanalyst. He is also renowned for his redefinition of sexual desire as the primary motivational energy of human life which is directed toward a wide variety of objects, as well as his therapeutic techniques, including the use of free association, his theory of transference in the therapeutic relationship, and the interpretation of dreams as sources of insight into unconscious desires.-----------In 1930, Freud received the Goethe Prize in appreciation of his contribution to psychology and to German literary culture. Three years later the Nazis took control of Germany and Freud's books featured prominently among those burned by the Nazis. In March 1938, Nazi Germany annexed Austria in the Anschluss. This led to violent outbursts of antisemitism in Vienna, and Freud and his family received visits from the Gestapo. Freud decided to go into exile "to die in freedom". He and his family left Vienna in June 1938 and traveled to London. A heavy cigar smoker, Freud endured more than 30 operations during his life due to oral cancer. In September 1939 he prevailed on his doctor and friend Max Schur to assist him in suicide. After reading Balzac's La Peau de chagrin in a single sitting he said, "My dear Schur, you certainly remember our first talk. You promised me then not to forsake me when my time comes. Now it is nothing but torture and makes no sense any more." Schur administered three doses of morphine over many hours that resulted in Freud's death on September 23, 1939.[15] Three days after his death, Freud's body was cremated at Golders Green Crematorium in England during a service attended by Austrian refugees, including the author Stefan Zweig. His ashes were later placed in the crematorium's columbarium. They rest in an ancient Greek urn which Freud had received as a present from Marie Bonaparte and which he had kept in his study in Vienna for many years. After Martha Freud's death in 1951, her ashes were also placed in that urn. Golders Green Crematorium has since also become the final resting place for Anna Freud and her lifelong friend Dorothy Burlingham, as well as for several other members of the Freud family.
