The Wildenstein Plattner Institute, Inc., (WPI) is a 501(c)(3) private foundation cofounded in 2016 by Guy Wildenstein, president of Wildenstein & Company; and Hasso Plattner, a leading entrepreneur in digital technology and an international benefactor of arts and education.

The WPI maintains its executive and administrative office in New York City and conducts research through the Fonds WPI in Paris. We are also assisted by a technical team in Berlin to develop our forthcoming database and Digital Catalogue.

The WPI relies on the opinions of scholars and specialists in the field who serve on our catalogue raisonné vetting committees.  As a matter of policy, we do not disclose the names of our committee members to the public.
