Mathilde Arnoux is an art historian specializing in transcultural processes in Europe of the 19th and 20th century. She is Research Director and Head of French Publications at the German Center for Art History in Paris. Her PhD obtained from Université Paris IV in 2003 on the reception of German paintings by French museums between 1871 and 1981 was a starting point to question the linear logic of ‘introduction, dissemination, and reception’ that often determines the analysis of relationships in the form of circulation phenomena. Since then, each of her research projects is in its own way part of a reflection on relationality (the ability to relate) and its multi-layered nature, focusing especially on processes of interaction, constitution, and transformation: the edition of the correspondence between Henri Fantin-Latour and Otto Scholderer, 1858–1902 (2004–2009); the team work around the ERC-funded project “OwnReality – To Each His Own Reality. The Notion of the Real in the Fine Arts of France, West Germany, East Germany and Poland between 1960 and 1989” (2011–2016) which led to her habilitation in 2017; the seminar and publication project with Anne Zeitz around the notion of polyphony in contemporary art (2021–2025).
