When Gregor Weber saw a painting by the Dutch Baroque painter Johannes Vermeer for the first time as a young boy, the sight made him lose his senses. A moment that determined his entire life. Today, Gregor Weber is one of the most important Vermeer experts and art historians in the world. In the 17th century, Vermeer created entire universes in a narrow corner of a room; his mastery continues to puzzle art history to this day. Perspective, composition, the colored shadow: Vermeer is known for the magic of contourless drawing. He created the "Girl with the Pearl Earring" or the "Street in Delft." Shortly before his retirement, Gregor Weber faces his most important task: curating the largest Vermeer exhibition of all time for Amsterdam's renowned Rijksmuseum. But Vermeer's paintings are now scattered around the globe. And shortly before the opening, American scholars claim that one of the central paintings is not by Vermeer at all.
