Sigmund Freud (born May 6, 1856 – died September 23, 1939) was an Austrian neurologist best known as the founder of psychoanalysis. His work laid the foundation for modern theories of personality, therapy, and human behavior.
Born in Freiberg in the Austrian Empire (now the Czech Republic), Freud studied medicine at the University of Vienna. He initially worked in neurology but later turned his focus to the unconscious mind, developing groundbreaking ideas such as the Oedipus complex, defense mechanisms, and dream interpretation.
Freud's theories were influential and controversial, shaping not only psychology but also literature, philosophy, and art. Despite criticism and evolving scientific views, his legacy endures in psychoanalysis and cultural thought.
He spent his final years in London after fleeing Nazi-occupied Austria in 1938, passing away from cancer the following year.

Freud introduced psychoanalysis as a method for treating psychopathology through dialogue between a patient and a therapist. His model of the psyche—comprising the id, ego, and superego—remains a cornerstone of psychoanalytic theory.
Though often debated, Freud’s ideas revolutionized the understanding of human nature. Concepts such as repression, the unconscious, and Freudian slips entered common discourse, reflecting his widespread cultural influence.
Sigmund Freud’s pioneering work continues to inform psychology, psychotherapy, and cultural theory. Despite changes in scientific perspectives, his influence is evident in countless disciplines and public consciousness.
