Johannes Warnardus Bilders was a Dutch landscape painter and founder of the Hague School.
He began his studies with Jan Lodewijk Jonxis, and moved after a trip to Germany to Oosterbeek, which was also called in reference to the French school of Barbizon the "Dutch Barbizon". There he later became one of the central figures of the Hague School, which included other artists such as Anton Mauve, Paul Gabriel and his son Gerard Bilders.
In his later career he changed jobs several times between Utrecht, Amsterdam and Oosterbeek.
In the Belgian village of Oosterbeek he met with other landscape painters and became the teacher of the following artists, such as the Jacob brothers, who later became one of the founders of the "Hague School".
Bilders made numerous studies according to nature and developed his distinctive style mainly through this independent study.
The characteristic romantic view of landscape lends his paintings a poetic-transfigured mood.
Paintings of paintings can be found in many private collections and Dutch museums.
