↑"Guggenheim Museum Quietly Removes Sackler Name" (انگلیسی جه). ۱۰ مه۲۰۲۲. Retrieved 29 September2025. New York's Guggenheim Museum is the latest art institution to remove the name of the Sackler family. Until last week, the Sacklers were honored as the namesakes of the institution’s Center for Arts Education. There was no public announcement at the time, but the name was quietly erased.{{cite web}}: Check date values in: |access-date= و |date= (help)نگهداری یادکرد:زبان ناشناخته (link)
↑"Guggenheim Museum Restitutes Ernst Ludwig Kirchner Painting to Heirs of Jewish Collector" (انگلیسی جه). ۴ اکتبر۲۰۱۸. Retrieved 5 February2026. The Solomon R. Guggenheim Foundation announced today that it will restitute a painting by German Expressionist Ernst Ludwig Kirchner to the heirs of the German Jewish art dealer Alfred Flechtheim (1878–1937).According to a statement issued by the museum, the Guggenheim Foundation spent two years investigating the provenance of Ludwig Kirchner’s Artillerymen, 1915. It learned that the work was in the possession of Flechtheim’s niece, Rosi Hulisch—who committed suicide before she was to be shipped to a concentration camp—when it was acquired by Kurt Feldhäusser, a member of the Nazi party, in 1938.After Feldhäusser was killed in Germany in 1945, his art collection was left to his mother, who consigned it to the Weyhe Gallery in New York a few years later. Morton D. May of St. Louis, Missouri, purchased Artillerymen in 1952 and donated it to the Museum of Modern Art in New York in 1956. In 1988, the painting was transferred by MoMA to the Solomon R. Guggenheim Foundation in exchange for other works.The Guggeneheim claims that at the time it did not realize that the painting had a questionable history because it relied on Donald E. Gordon’s catalogue raisonné of Ludwig Kirchner’s work. Published in 1968, the catalogue incorrectly states that Artillerymen had been owned by German collector Hermann Lange before it entered Feldhäusser’s collection{{cite web}}: Check date values in: |access-date= و |date= (help)
↑Philip Boroff (۱۸ ژوئن۲۰۰۹). "Wayback Machine"(PDF). Judge Slams MoMA, Guggenheim on Secret Holocaust Art Agreement. Retrieved 5 February2026. In 2007, lawyers for Schoeps contacted MoMA and the Guggenheim to demand the return of the Picassos. They said the works were sold before World War II “under duress from Nazi persecution” according to court records.The 1906 “Boy Leading a Horse,” now at MoMA, and the Guggenheim’s 1900“Le Moulin de la Galette” had been in the private collection of Paul von Mendelssohn-Bartholdy, a German Jewish banker who died in 1935. Schoeps’s grandmother was a sister of von Mendelssohn-Bartholdy.Valued at $150 MillionBoth paintings were later acquired by the museums and are highlights of the collections. Dealers said MoMA’s Picasso is valued at over $100 million and the Guggenheim’s could command more than $50 million.The museums jointly filed a complaint in federal court in 2007, asking that the courts affirm their ownership. They argued that the paintings were not sold on account of duress; instead they were given by von Mendelssohn-Bartholdy to his wife and were sold by 1935 to Galerie Thannhauser, which had branches in Berlin and Lucerne, Switzerland, according to the museums’ complaint. Last year, in a motion to dismiss the complaint, Schoeps accused MoMA and the Guggenheim of being“knowing possessors of art coerced from Jewish victims in Nazi Germany.” He said they employed “blitzkrieg tactics against Holocaust victims and their heirs” calculated to “deflect attention from the many serious breaches of fiduciary duty” that the museums committed by keeping the paintings.{{cite web}}: Check date values in: |access-date= و |date= (help)
↑Randy Kennedy (۲ فوریه۲۰۰۹). "Museums and Heirs Settle Dispute Over Picasso". Museums and Heirs Settle Dispute Over Picasso (انگلیسی جه). Retrieved 5 February2026. Two museums announced Monday that they had reached a settlement with heirs of the original owner of two Picasso paintings, including “Boy Leading a Horse,” who contended that they had been sold under duress in Nazi Germany. The terms of the agreement, reached as a trial was about to begin in federal court in Manhattan, were not disclosed. But the Museum of Modern Art and the Solomon R. Guggenheim Museum said in a statement that they would continue to own the works. The suit involved “Le Moulin de la Galette,” given to the Guggenheim in 1963 by the art dealer Justin K. Thannhauser, and “Boy Leading a Horse,” sold by Mr. Thannhauser to William S. Paley, who donated it to MoMA in 1964.{{cite web}}: Check date values in: |access-date= و |date= (help)نگهداری یادکرد:زبان ناشناخته (link)
