Robert Campin
(c. 1375 – 1444)
 

Robert Campin now usually identified with the Master of Flémalle (earlier the Master of the Merode Triptych, before the discovery of three other similar panels), was a master painter who, along with Jan van Eyck, initiated the development of early Netherlandish painting, a key development in the early Northern Renaissance.

Portrait of a Fat Man (or Portrait of a Stout Man or Portrait of Robert de Masmines) are names given to two near-identical oil on panel paintings attributed to the Early Netherlandish artist Robert Campin. Both versions are dated c. 1425, and are in the Gemäldegalerie, Berlin and Museo Thyssen-Bornemisza, Madrid.
