“Homo Neubau”: An exhibition featuring Ernst Grünfeld

In the winter of 1921/22, Ernst Grünfeld developed a revolutionary chess opening. Almost a hundred years later, the Viennese, who became a professional player out of necessity and joined the NSDAP because of his Jewish-sounding name, is the unlikely star of an exhibition in his hometown. Stefan Löffler visited it. | Photos, if not otherwise indicated: Collection Michael Ehn
