Ingres, an important influence, told the 21-year-old to draw lines. He met Manet copying at the Louvre, and was introduced by him to Renoir, other Impressionists and Zola at their regular café. Cassatt as well as Manet became close friends, Cassatt clearly influenced by him. He was one of Mallarmé’s many artist friends, and intermittently close with Gauguin, but his own anti-semitism led him to break off with Cézanne and Renoir at the time of the Dreyfus affair. Sickert, whom he mentored, was described as one of his few friends and many admirers. Valadon persuaded him, almost blind, to leave his apartment.
