Lady with a Fan, Lady with a False Provenance

 

Why did the National Gallery of Victoria originally list a "Dr. Grunden of Hamburg" in the provenance of this 17th century painting by Gerard ter Borch, Lady with a Fan? 

When Max Emden's grandson, Juan Carlos Emden, found, in Australia, the painting that had belonged to his family before Hitler came to power, he knew the provenance was wrong.

Did the Musée de l'Orangerie make a spelling error in the name of a Holocaust victim in the provenance of this Cézanne?

Max Silberberg was a Jewish art collector in Breslau murdered by the Nazis.

Is he the same person as "Silbergerg" in the provenance text of "Fruits, serviette et boîte à lait" by Paul Cézanne? 

Suspicious provenance errors: Manet's Mellon

Mrs Kurt Riezler (née Käthe Liebermann, daughter of Max Liebermann) was previously mis-identified as Liezler

 Why does it matter? Because her family was persecuted by the Nazis and she herself was a refugee.
