Sigmund Freud
The father of psychoanalysis, Sigmund Freud, made significant contributions to the fields of psychology, psychiatry, and psychotherapy during his lifetime (1856–1939).
He created therapeutic methods like free association and identified transference, which are still used in Western culture today. He also investigated how thoughts affect the unconscious mind and how to interpret dreams.
Walt Whitman
Walt Whitman, a poet and writer from the United States, is frequently referred to as the inventor of free verse. He was renowned for his historical realism and commitment to the truth.
Art historian Mary Whitall Smith Costelloe claims that “Without Walt Whitman and Leaves of Grass, you cannot truly comprehend America. No student of the philosophy of history can do without him since he has articulated that civilisation, or put it more accurately, “up to date,” as he would say.”
