‘titrebSummary’/titrebprofessor emérite des Universités, Armand Mattelart is an important and original figure in the field of media studies: born in Belgium, trained in France and having pursued the first part of his academic career in Chile, he devoted much of his work (part of which was carried out with his wife Michèle Mattelart) to the global dimension of communication and media. This researcher also embodies, through his background, a research for which he is more critical than an intellectual tour of analysis but rather a political gesture.
