Claude Monet
(1840 - 1926)

A lot of artists made a reaction on yesterday’s painting by Manet, also Monet:

Le Déjeuner sur l'herbe (English: Luncheon on the Grass) is an 1865–1866 oil-on-canvas painting by Claude Monet, produced in response to the 1863 work of the same title by Édouard Manet. It remains unfinished, but two large fragments (central and left panels) are now in the Musée d'Orsay in Paris, while a smaller 1866 version is now in the Pushkin Museum in Moscow. 

Monet originally wanted to submit the painting to the Salon of 1866, but he underestimated how long it would take him to transfer his sketches to a life-size canvas, so it remained unfinished by the time of the exhibition. 

Monet later offered the large canvas of Déjeuner to his landlord in place of rent. When Monet bought it back from his landlord, it was badly damaged from the damp environment in which it was stored.

Monet had to cut it up in order to preserve the non-damaged parts.
