Willem Roelofs (March 10, 1822, Amsterdam - May 12, 1897, Berchem) was a Dutch painter, water-colourist, etcher, lithographer and draughtsman. Roelofs was one of the forerunners of the Dutch Revival art, after the Romantic Classicism of the beginning of the 19th century, which led to the formation of The Hague school. His landscapes, especially the early ones with their dominating cloudy skies, demure bodies of water and populated with cattle, are typical for the School of Barbizon.
