Born in France, he studied painting at the Swiss Academy and forged links with the future Impressionists. In 1886, Zola, his friend Zola, dates him, uses him as a model to describe a failed painter. This is the end of their long friendship. On the other hand, he still has a very good relationship with Pissarro, whom he worships as a master: he works with him for two years but in 1877, he splits off from this movement. His research made him the precursor of cubism: drawing and colour became inseparable from the arrangement of the painting, which was organized from the inside.
