A violent attack against Émile Zola

In 1887, the writer J.-H. Rosny aîné violently distanced himself from the naturalist movement of Émile Zola. With four other colleagues, he wrote an open letter to reproach the master for his search for the vulgar and his profound medical and scientific ignorance. This rupture marked a turning point in his work, pushing him to explore new forms of evolution in his stories such as Les Xipéhuz.
