An old half-timbered house in the Odenwald and a long-forgotten poetry album filled with good wishes, written in beautiful Sütterlin script in a friendship book, pose a mystery: Who was that girl named Natalie Rambaud, to whom the book belonged? What can still be learned today about her life and the fate of those people who wrote in the Art Nouveau album more than 100 years ago in the Waldensian colony of Rohrbach, Wembach, Hahn? 'In Remembrance' attempts, true to their motto: Lux lucet in tenebris - the light shines in the darkness, to bring light into the darkness of the past and preserve it from being forgotten. The partly very revealing poetry verses, shaped by the thoughts of that time, have been transcribed into modern script for better readability. With original illustrations of the pages, information about Grand Duke Ernst Ludwig of Hesse-Darmstadt, and the history of the Waldensians in the Odenwald.
