The Cologne-based photographer and blogger Christian Herrmann has travelled Eastern Europe for years to document traces of Jewish life before the Holocaust. Here, in a belt between the Baltic and Black Seas, lived the majority of European Jews. During the Second World War, almost all of them were murdered by the German occupiers and their collaborators. What remains are traces of Jewish life: destroyed or misappropriated synagogues, overgrown cemeteries, tombstones in the street paving, and traces of home blessings on door jambs. His book In schwindendem Licht / In Fading Light presents 110 photos of Jewish heritage sites in 57 cities, towns and villages in Ukraine, the Republic of Moldova, Poland, Hungary and Romania. Weve asked him some question about his photographs by e-mail.
