In 1997, invited by Daniel Wildenstein, Marc Restellini decided to undertake the Catalogue raisonné of Amedeo Modigliani’s works, imposing new scientific criteria never before used in the field of research on works of art. After 18 years of exemplary collaboration, Marc Restellini and the Wildenstein Institute decided, by a mutual decision, to part, Marc Restellini wishing to evolve on his own. In 2015, the Catalogue Raisonné Amedeo Modigliani is henceforth transferred to Institut Restellini, being taken up with new methods, even more modern and scientifically extensive. It will be enhanced by the drawings, which had been set aside with the Wildenstein Institute.

Amedeo Modigliani Catalogue Raisonné of the Oil Paintings was published in May 2026, bringing to an end over 25 years of research on this artist. Marc Restellini has access to an outstanding group of archives, including those of the artist’s main collectors, Léopold Zborowski, Jonas Netter, Paul Guillaume, and Roger Dutilleul, as well as an unique deposit of hundreds of scientific analyses.

Other catalogues will then be developed, in the fields of ancient, modern and contemporary art.
