Sigmund Freud (6 May 1856-23 September 1939) was an Austrian neurologist who discovered Psychoanalysis. He is best remembered for his theories related to the subconscious mind and the mechanism of repression. Freud can be best termed as prolific essayist, drawing on psychoanalysis to contribute to the history, interpretation and critique of culture. Though some of his critics believe that his psychoanalytical theory is attributed to his use of cocaine in his earlier days.
“The Interpretation of Dreams” remains by far the best of his works.
