Sigmund Freud

Sigmund Freud is widely recognized as the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst. His theories on the unconscious mind, defense mechanisms, and the interpretation of dreams profoundly influenced psychology, psychiatry, and Western thought.

For readers new to Freud, "The Interpretation of Dreams" is often considered his magnum opus and a foundational text, though it can be dense. A more accessible starting point might be "Introductory Lectures on Psychoanalysis" or "Civilization and Its Discontents," which offer broader overviews of his theories.

Sigmund Freud did not use any known pen names; all of his published works are attributed directly to him.
