A group of French painters in the mid-19th century who embraced plein-air painting and sought to elevate the status of the landscape as an independent  subject. The name of the school was taken from the village of Barbizon on the edge of the Forest of Fontainebleau,  where several of the painters worked. Prominent Barbizon School painters include Théodore Rousseau, Camille Corot, Jean-François Millet, and Charles-François Daubigny.  Web resource here.
