When did the Salon de Paris reject Édouard Manet’s painting 'Luncheon on the Grass'?

Le Déjeuner sur l'herbe (English: The Luncheon on the Grass) originally titled Le Bain (The Bath) is a large oil on canvas painting by Édouard Manet created in 1862 and 1863. Rejected by the Salon de Paris in 1863, Manet seized the opportunity to exhibit this and two other paintings in the 1863 Salon des Refusés, where the painting sparked public notoriety and controversy. The piece is now in the Musée d'Orsay in Paris. A smaller, earlier version can be seen at the Courtauld Gallery, London.

The painting features a nude woman casually lunching with two fully dressed men. Her body is starkly lit and she stares directly at the viewer. The two men, dressed as young dandies, seem to be engaged in conversation, ignoring the woman. In front of them, the woman's clothes, a basket of fruit, and a round loaf of bread are displayed, as in a still life. In the background, a lightly clad woman bathes in a stream. Too large in comparison with the figures in the foreground, she seems to float above them. The roughly painted background lacks depth, giving the viewer the impression that the scene is not taking place outdoors, but in a studio. This impression is reinforced by the use of broad "studio" light, which casts almost no shadows. The man on the right wears a flat hat with a tassel, a kind normally worn indoors.
