About

The Sonnabend Collection Foundation, based in New York, was established in 2008 with the purpose of preserving, managing, and disseminating the important art collection assembled by Ileana Sonnabend and Michael Sonnabend, in collaboration with Antonio Homem and Nina Sundell. It is a non-profit organization (501(c)(3)), dedicated to the arts and culture, and seeks to make the works of the collection accessible to the general public. The mission of the Foundation focuses on lending works to museums and educational institutions worldwide, thereby enhancing the study and visibility of modern and post-war art. Through collaborations with leading organizations in Asia, Europe, America, and South America, the Foundation contributes to international artistic exchange and broadens access to one of the most emblematic bodies of work of the post-war period. The collection includes landmark works of Pop Art, Arte Povera, Minimalism, and Conceptual Art, with artists such as Andy Warhol, Roy Lichtenstein, Jasper Johns, Robert Rauschenberg, Claes Oldenburg, Michelangelo Pistoletto, Jannis Kounellis, Jeff Koons, among many others.As of November 29, 2025, 96 works from the Foundation’s Collection will be exhibited in Mantua, Italy, at a new museum dedicated to the Foundation, which will bear the name Sonnabend Collection Mantova. This new permanent venue will serve as a central reference point for the presentation and study of the Collection in Europe.
