Claude Lévi-Strauss was a French anthropologist, well-known for his development of structural anthropology. He was born in Belgium to French parents who were living in Brussels at the time, but he grew up in Paris. His father was an artist, and a member of an intellectual French Jewish family. Lévi-Strauss studied at the University of Paris. From 1935-9 he was Professor at the University of Sao Paulo making several expeditions to central Brazil. Between 1942-1945 he was Professor at the New School for Social Research. In 1950 he became Director of Studies at the Ecole Practique des Hautes Etudes. In 1959 Lévi-Strauss assumed the Chair of Social Anthroplogy at the College de France. His books include The Raw and the Cooked, The Savage Mind, Structural Anthropology and Totemism (Encyclopedia of World Biography). Some of the reasons for his popularity are in his rejection of history and humanism, in his refusal to see Western civilization as privileged and unique, in his emphasis on form over content and in his insistence that the savage mind is equal to the civilized mind. Lévi-Strauss did many things in his life including studying Law and Philosophy. He also did considerable reading among literary masterpieces, and was deeply immersed in classical and contemporary music. Lévi-Strauss was awarded the Wenner-Gren Foundation's Viking Fund Medal for 1966 and the Erasmus Prize in 1975. He was also awarded four honorary degrees from Oxford, Yale, Havard and Columbia. Strauss held several memberships in institutions including the National Academy of Sciences, the American Academy and Institute of Arts and Letters, the American Academy of Arts and Sciences, and the American Philosophical Society (Encyclopedia of World Biography).

Karl Abraham was an early important and influential German psychoanalyst, and a collaborator of Sigmund Freud, who called him his 'best pupil'. In 1907, he had his first contact with Freud, with whom he developed a lifetime relationship. Returning to Germany, he founded the Berliner Society of Psychoanalysis in 1910. He was the president of the International Psychoanalytical Association from 1914 to 1918 and again in 1925. Abraham collaborated with Freud on the understanding of manic-depressive illness, leading to Freud's paper on 'Mourning and Melancholia' in 1917. He was the analyst of Melanie Klein during 1924-1925, and of a number of other British psychoanalysts, including Edward Glover, James Glover, and Alix Strachey. He was a mentor for an influential group of German analysts, including Karen Horney, Helene Deutsch, and Franz Alexander. In the oral stage of development, the first relationships children have with objects (caretakers) determine their subsequent relationship to reality. Oral satisfaction can result in self-assurance and optimism, whereas oral fixation can lead to pessimism and depression. Moreover, a person with an oral fixation will present a disinclination to take care of him/herself and will require others to look after him/her. This may be expressed through extreme passivity (corresponding to the oral benign suckling substage) or through a highly active oral-sadistic behaviour (corresponding to the later sadistic biting substage). In the anal stage, when the training in cleanliness starts too early, conflicts may result between a conscious attitude of obedience and an unconscious desire for resistance. This can lead to traits such as frugality, orderliness and obstinacy, as well as to obsessional neurosis as a result of anal fixation (Abraham, 1921). In addition, Abraham based his understanding of manic-depressive illness on the study of the painter Giovanni Segantini: an actual event of loss is not itself sufficient to bring the psychological disturbance involved in melancholic depression. This disturbance is linked with disappointing incidents of early childhood; in the case of men always with the mother. This concept of the prooedipal “bad” mother was a new development in contrast to Freud’s oedipal mother and paved the way for the theories of Melanie Klein (May-Tolzmann, 1997). Another important contribution is his work “A short study of the Development of the Libido” (1924b), where he elaborated on Sigmund Freud’s “Mourning and Melancholia” (1917) and demonstrated the vicissitudes of normal and pathological object relations and reactions to object loss. Abraham (1920) also showed interest in cultural issues. He analyzed various myths suggesting their relation to dreams (1909) and wrote an interpretation of the spiritual activities of the Egyptian monotheistic Pharaoh Amenhotep IV (1912). Abraham died on 25 December 1925 from complications of a lung infection and may have suffered from lung cancer.
