About
The Sonnabend Collection Foundation, based in New York, was established in 2008 to preserve, manage, and disseminate the significant art collection assembled by Ileana Sonnabend and Michael Sonnabend, in collaboration with Antonio Homem and Nina Sundell.
A non-profit 501(c)(3) organization dedicated to arts and culture, the Foundation strives to make the collection accessible to the public. Its mission centers on lending works to museums and educational institutions worldwide, thereby supporting scholarship and increasing the visibility
of modern and post-war art. Through collaborations with leading organizations across Asia, Europe, the Americas, and South America, the Foundation contributes to international artistic exchange and expands access to one of the most emblematic bodies of work from the post-war
period.
The collection includes landmark works of Pop Art, Arte Povera, Minimalism, and Conceptual Art, featuring artists such as Andy Warhol, Roy Lichtenstein, Jasper Johns, Robert Rauschenberg, Claes Oldenburg, Michelangelo Pistoletto, Jannis Kounellis, and Jeff Koons, among many others.
