Lissitzky v. Beyeler Foundation
Mount v. Sadik, No. 78-cv-2279 (WCC), (S.D.N.Y. Oct. 26, 1978), aff'd on reconsideration, (S.D.N.Y. Apr. 10, 1980).
In 1926, Sophie Küppers-Lissitzky loaned 13 artworks to the Provinzialmuseum (later the Landesmuseum) in Hanover, before leaving Germany for Russia, where she married the artist El Lissitzky. The works were seized as part of the Nazi campaign against degenerate art in 1937. In 1941, following her husband’s death, Sophie was exiled to Siberia, where she died in 1978.
