Sigmund Freud was an Austrian neurologist who became known as the founding father of psychoanalysis.
Freud qualified as a Doctor of Medicine at the University of Vienna in 1881, and then carried out research into cerebral palsy, aphasia and microscopic neuroanatomy at the Vienna General Hospital. He was appointed a University lecturer in neuropathology in 1885 and became a Professor in 1902.
In creating psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst, Freud developed therapeutic techniques such as the use of free association and discovered transference, establishing its central role in the analytic process. Freudís analysis of his own and his patients dreams as wish-fulfilments provided him with models for the clinical analysis of symptom formation and the mechanisms of repression as well as for further elaboration of his theory of the unconscious as an agency disruptive of conscious states of mind. Freud postulated the existence of libido, an energy with which mental process and structures are invested and which generates erotic attachments, and a death drive, the source of repetition, hate, aggression and guilt. In his later work Freud drew on psychoanalytic theory to develop a wide-ranging interpretation and critique of religion and culture.
