Trustees for the family of Mondrian's heir Harry Holtzman sued the Philadelphia Museum of Art in December 2021 for a painting the Nazis took from a Hanover museum in 1937, valued at over $100 million
Piet Mondrian died in New York in 1944 and named the artist Harry Holtzman his heir. Holtzman died in 1987. In December 2021 the three trustees of a Holtzman family trust, Jason, Jackie and Madalena McManus Holtzman, sued the Philadelphia Museum of Art for Composition with Blue (1926), a 60 by 60 cm painting. The complaint says Mondrian consigned it in 1927 to Sophie Kuppers, who stored it at the Provinzialmuseum in Hanover. Nazi authorities seized it in 1937 and passed it to dealer Karl Buchholz; his agent Curt Valentin sold it in New York in 1939. Collector A. E. Gallatin acquired it and gave it to the museum in 1952. The complaint puts its value above $100 million and relies on the Holocaust Expropriated Art Recovery Act of 2016 for timeliness. The museum said it would defend against what it called a meritless claim and said Holtzman knew of its ownership for about 43 years and never claimed it. The museum removed the case to the US District Court for the Eastern District of Pennsylvania on 11 January 2022. On 7 July 2022 Judge John Milton Younge denied the plaintiffs' motion to send it back to state court. The outcome is not confirmed†.
An heir who waits decades to claim a work lets the holder argue delay, and limitation statutes can decide a case that history does not.
