Louis Valtat (born in 1869 and died in 1952 ) was a French painter and printmaker associated with the Fauves ("the wild beasts", so named for their wild use of color)and also  noted as a key figure in the stylistic transition in painting from Monet to Matisse.

Furthermore, Paul Signac organized a joint exhibition at la Galerie Durand Ruel where Louis Valtat presented twenty paintings entitled “Notations d’Agay in 1899”.
