Raoul Meyer collected a large number of French impressionist paintings before World War II. His art collection was seized by the Nazis during the occupation of France and the Vichy government. After the war he worked to recover the looted paintings. In 1953, he sued Swiss art dealer Christoph Bernoulli, who had bought the Pissarro work. A Swiss judge dismissed the suit, saying a five-year window for such lawsuits had passed. The museum has cited the Swiss suit to prove that it can keep the painting. The painting changed hands several times before being donated to the university in a bequest from Aaron and Clara Weitzenhoffer.

Unbeknownst to Raoul Meyer and his heir, La Bergère entered the David Findlay Galleries in New York in the fall of 1956 as part of an exhibit of "French Paintings of the XIXth and XXth centuries" from the collection of E. J. van Wisselingh & Co., an art dealer based out of Amsterdam, Holland.

In its motion to dismiss the case, the university contended that a Swiss court's 1956 ruling against Meyer's father deserves to be respected because those proceedings were "full and fair," and should not be revisited in the United States. But a new era of international accords recognizes that Jews' claims to Nazi-looted property in fact often were not handled fairly by postwar authorities in Europe.

Dr. Meyer's mother, grandmother, uncle and brother died in Auschwitz. Her father hid the painting in a French bank that was looted in 1941 by the Nazis, and the work vanished in the murky universe of art market collaborators and middlemen. Decades later, in 2012, she discovered the whereabouts of "La Bergère," or "Shepherdess Bringing in Sheep," in the Fred Jones Jr. Museum of Art, at the University of Oklahoma. In 2016, she brokered a compromise to rotate it between the university and a French museum.
