At the Paul Cézanne exhibition at the Fondation Beyeler on Friday afternoon, I was taken aback to read the provenance of several of the paintings: they are on loan from the Kunsthaus Zürich's controversial collection of the Swiss arms manufacturer Emil Bührle (1890-1956). Not only did Bührle make a fortune selling arms to Germany under Adolf Hitler, the provenance of many works in his collection is suspicious at best. But when I told my wife Andrea that I had noticed that, she told me that when she had gone on a tour a few weeks ago, the guide made several comments on the history of the works from the Bührle collection. (Andrew Shields, #111Words, 26 April 2026)
