Thierry Groensteen (born April 18, 1957 in Brussels) is one of the leading French-speaking comics researchers and theoreticians, whose work has found repercussions beyond this field. In 1984, he became the editor-in-chief of the old fanzine Schtroumpf – Les Cahiers de la bande dessinée, transforming it into one of the first gestures that would lead to a serious comics criticism in France and beyond, integrating it into discussions on art and culture. His work as the organizer of the famous Colloque de Cérisy, in 1987, titled Bande dessinée, récit et modernité (“Comics, narrative and modernity”), would also be an important contribution. As the director of Angoulême’s Musée de la bande dessinée, during the early 1990s, he worked in many projects from exhibitions and the respective catalogs, to monographs on several authors, or themes and collections presented by the Angoulême Museum. He was also the director of the first run of its official magazine, 9ème Art. He was the founder and editor at Éditions de L’An 2, before this publishing house was integrated by Actes Sud. He is a lecturer at the École européenne supérieure des Arts et technologies de l’image.
