Some restitution cases for artworks that passed through the Nazi Kurt Feldhäusser on their way to the Museum of Modern Art in New York include:
- Artillerymen in the Shower (Kirchner) which had been owned by Alfred Flechtheim and which had been given a false provenance, restituted after litigation by the Guggenheim which had acquired it from the MoMA- Over Vitebsk (Chagall) which (also) had been owned by Alfred Flechtheim and which also had been given a false provenance, restituted secretly by the MoMa to the Matthiesen heirs in exchange for a $4 million payment, after initially refusing restitution on the grounds that repayment of a debt and not Nazis had been involved ("MoMA, in its records on its website, said the gallery had turned over the Chagall painting to a major German bank in 1934 “in exchange for debt"- NYT)
- Sand Hills (Kirchner) which had been owned by Max Fischer and which had been given (sigh) a false provenance, restituted by the MoMa after the museum had initially refused mistakenly confusing the painting with another that had been seized from a German museum due to a sequence of errors
Kurt Feldhäusser was a Nazi Party member linked to art looted from German Jews starting in 1933 or seized from museums in the Nazi "Degenerate Art" campaign of 1937-8.
