Belongs here: Carl Jung, Abraham Maslow, Henry Murray, George Kelly, Else Frenkel-Brunswik, Jane Loevinger, Mary Whiton Calkins, June Etta Downey, Sandra Bem and Walter Mischel. A figure whose personality theory is chiefly clinical, built for treatment rather than trait description, is filed under clinical psychology instead.
