In the museum, the Mondriaanhuis shows nine naturalist works from Mondrian’s early period. These landscapes and city views are from the Esser collection. In his time, the physician J.F.S. Esser (1877-1946) possessed one of the largest collections of Dutch modern art. Around 1912, the collection comprised eight hundred works of art, including no less than eighty works by Mondrian. These were all naturalistic canvases from the painter’s early period, as the collector could not appreciate abstract art very much. Mr Esser’s heirs have given the Mondriaanhuis nine works on long-term loan.
