Carl Jung, a Swiss psychiatrist and renowned psychoanalyst, revolutionized the field of psychology with his groundbreaking theories. Born in 1875, Jung developed the concept of the collective unconscious, which explored the depths of human psyche and the archetypes that shape our behavior. His analytical psychology emphasized self-realization and the integration of the conscious and unconscious mind. Jung's work on personality types, such as introversion and extroversion, continues to greatly influence modern psychology. Throughout his career, he collaborated closely with Sigmund Freud before eventually diverging due to differing viewpoints. A prolific writer, Jung left behind a legacy of insightful publications, including "The Red Book." His contributions to the field are revered to this day, making him one of the most influential figures in psychology.
