Eugène Bidau was a French painter, most notable for his still lifes. Bidau was born at La Roche-sur-Yon, Vendée in the Pays de la Loire region in western France.
He studied under Baptiste-Joseph Lechat and the portrait and genre artist Léon-Désiré Alexandre (1817-86), both of whom exhibited at the Salon des Artistes Français in Paris.
Bidau then made his own debut at the Salon in 1863 and continued to exhibit there for many years, showing for instance floral pieces in 1864 and 1865 and then a work titled Le panier renversé; Fleurs et fruits in 1867.
