Émile François Zola (1840 - 1902), was a French writer, of the literary schools of naturalism and theatrical naturalism. He is also responsible for the popularity, in the English-speaking world, of the phrase J'accuse! as an expression of accusation and outrage against a powerful person suspected of wrongdoing.
Manet's portait of Zola, painted in 1868, now resides at the Musée d'Orsay, in Paris, France.
