ABRAHAM, KARL

German psychiatrist and pioneer in the development of psychoanalysis. A close associate of Sigmund Freud, he introduced psychoanalysis into Germany, analyzing patients and students (including numerous subsequently prominent practitioners). His activities made Berlin an international psychoanalytic center. Abraham's investigations dealt with the development of the libido (the primitive drives of psychoanalytic theory), the hostility of women to men, the roots of manic-depressive conditions, and other psychiatric problems.
