Iris Meder (1965–2018) was a Vienna-based art historian. A large portion of her work and library is dedicated to the Danube region. On 15 November 2019, the Österreichische Gesellschaft für Architektur (Austrian Society for Architecture, ÖGFA) inaugurated the Archive Iris Meder. The author examines how Iris Meder, who grew up on the western border of Baden-Württemberg, Germany, became an expert in her field. Historical chronicles and the experience of the present are in accord: seldom can a private library’s books be preserved as a coherent and recognizable collection. The author gives a glimpse into the inner workings of an impressively versatile, highly knowledgeable independent scholar, and the journey undertaken by the ÖGFA to make her archive available to the public.
