Freud, Sigmund.

Sigmund Freud is the founder of psychoanalysis and the discoverer of the unconscious. With his epoch-making contributions he initiated a fundamental transformation in the self-understanding of Western men and women. In his lifetime, Freud published 24 books and 123 articles containing some 90 specifically Freudian concepts that form the core of his theory. With this corpus and thanks to a carefully planned strategy for disseminating his ideas, Freud exerted a profound influence in all branches of the arts and humanities.
