Jacques Goudstikker was a Jewish Dutch art dealer who fled the Netherlands when it was invaded by Nazi Germany during World War II, leaving three furnished properties and an extensive and significant art collection including over 1200 paintings, many of which had been previously catalogued as "Old Masters". The entire collection, which had been surveyed by Hermann Goering himself, was subsequently looted by the Nazis. Between the two World Wars, Jacques Goudstikker had been the most important Dutch dealer of Old Master paintings, according to Peter C. Sutton, executive director and CEO of the Bruce Museum of Arts and Science. Despite efforts of Goudstikker's widow after the war to regain possession of the collection, it was not until after her death that the Dutch government finally restituted 202 paintings to the Goudstikker family in 2006. To finance efforts to reclaim more of the stolen art, a large portion of them were sold at auction in 2007 for almost $10 million.
