In 1949, the museum was among the first to return a work that had been looted by the Nazis, when it returned Claude Monet's "The Seine at Asnières" to its rightful owner. The art dealer from whom they had purchased it reimbursed the museum. In 2002, the museum discovered that Ludolf Backhuysen's "A Man-O-War and Other Ships off the Dutch Coast", a 17th-century seascape painting under consideration for purchase by the museum, had been looted from a private European collection by the Nazis. The museum contacted the original owners, paid the rightful restitution, and the family allowed the museum to accession the painting into its collection, adding another painting to the museum's already prominent Dutch collection.
