Armand Guillaumin (1841 –1927) was a French impressionist painter and lithographer. Noted for their intense colours, Guillamin's paintings are represented in major museums around the world. He is best remembered for his landscapes of Paris, the Creuse département, and the area around Les Adrets-de-l'Estérel near the Mediterranean coast in the Provence-Alpes-Côte d'Azur region of France. Guillamin was called the leader of the École de Crozant, a diverse group of painters who came to depict the landscape in the region of the Creuse around the village of Crozant.
