Overview

The Holocaust Art Restitution Project (HARP) is a non-profit organization founded in 1997 by Marc Masurovsky, a former researcher for the U.S. Presidential Advisory Commission on Holocaust Assets. HARP is dedicated to the identification, documentation, and restitution of art and cultural property looted by the Nazis and their collaborators between 1933 and 1945. The organization operates as a research and advocacy group, providing expertise to claimants, museums, and governments on provenance research and restitution claims. Its work is rooted in the principles of the 1998 Washington Conference on Holocaust-Era Assets, which established non-binding principles for handling Nazi-confiscated art. HARP maintains a blog, "Plundered Art," which serves as a platform for articles, case studies, and commentary on ongoing restitution issues. The organization is based in Washington, D.C., and collaborates with international bodies, including the U.S. Holocaust Memorial Museum and European restitution commissions. Through its research, HARP aims to bring attention to the historical injustices of art looting and to promote just and fair solutions for original owners and their heirs.

History

The Holocaust Art Restitution Project (HARP) was founded in 1997 by Marc Masurovsky, a historian and provenance researcher who had previously worked for the U.S. Presidential Advisory Commission on Holocaust Assets. The organization emerged in response to growing international awareness of the failure to return artworks looted by the Nazis during World War II and the Holocaust. HARP's mission is to conduct research, document looted art, and advocate for the restitution of cultural property to original owners and their heirs. In its early years, HARP focused on creating databases of looted artworks and providing research support to claimants. The organization played a role in the 1998 Washington Conference on Holocaust-Era Assets, which produced the Washington Principles, a set of non-binding guidelines for handling Nazi-confiscated art. HARP has since been involved in numerous restitution cases, offering expertise on provenance and legal issues. The organization maintains a blog, "Plundered Art," which features articles by Masurovsky and others on topics such as the Washington Principles, specific restitution cases, and the challenges of provenance research. HARP continues to operate as a resource for researchers, journalists, and claimants seeking information on Holocaust-era looted art.
