"These were years of crisis not only for Schoenberg’s musical style but in his domestic life. He had made the acquaintance of the Viennese painters Oskar Kokoschka and Richard Gerstl, and in 1908 took up painting seriously. Gerstl, who had become a family friend, gave lessons to both him and his wife. During that summer he discovered that she was having an affair with Gerstl, with whom she then went to live. Later she was persuaded to return for the sake of the children; in November Gerstl committed suicide." (from the new grove biography of Arnold Schoenberg)
