Sigmund Freud

Sigmund Freud was a neurologist and the founder of psychoanalysis, revolutionizing the understanding of human personality.

Born in 1856, he studied medicine at the University of Vienna and later specialized in nervous disorders.

Freud developed theories about the unconscious mind, sexual and aggressive impulses, and defense mechanisms.

His seminal work, "The Interpretation of Dreams," was published in 1900.

Freud's ideas, though controversial, gained a following and led to the establishment of the International Psychoanalytic Association.

He applied his theories to various fields, including history, art, and literature.

In 1938, Freud fled Nazi-occupied Austria for London, where he died of cancer in 1939.
