Carl Gustav Jung
Carl Gustav Jung, a Swiss psychologist, lived from 1875 till 1961. In the beginning of his career he was a follower of Sigmund Freud, later he came to diagree with him and started an alternative school. He had, just as freud, a great influence on modern Psychology (and Psychiatry).Jung met freud in 1907 and he became a member of Freud's psychoanalitical society. In 1912 he resigned and founded his own school in Zurich. Jung believed that Freud overemphasized the role of sexual drive. He developed his own theory of the libido, arguing that the will to live was stronger than the sexual drive.
Jung classificated personalities into two types; introverts and extroverts. This classification is well accepted nowadays.
