As the years passed, Degas became isolated, due in part to his belief that a painter could have no personal life. The Dreyfus Affair controversy brought his anti-Semitic leanings to the fore and he broke with all his Jewish friends. His argumentative nature was deplored by Renoir, who said of him: "What a creature he was, that Degas! All his friends had to leave him; I was one of the last to go, but even I couldn't stay till the end."
