Abstract : This introduction stresses the scarcity of scientific studies on the Tubu, although these nomads occupy one fourth of the Sahara to the North of Lake Chad. To pay tribute to Charles and Marguerite Le Cœur, who initiated Tubu studies in Tibesti in the 1930's, this book publishes 7 articles on the Tubu by contemporary scientists, and republishes 10 previously scattered articles by Charles Le Cœur. The introduction underlines the value of the Le Cœur's contribution, and depicts the main aspects of Tubu social organization: the weakness of leadership, the role of clans, the wide extension of matrimonial prohibitions, the widespread cycle of livestock transfers which are set in motion by each marriage, insuring this society's flexibilty and resilience. This introduction then presents the papers of the 7 contributors to the book, and comments on the choice of Charles Le Cœur's articles. It shows how these diverse contributions converge in the light they shed on this pastoral society.
