Establishing the context within which organizers who staged spectacular popular science exhibitions for urban middle-class audiences and the physicians as well as activists who provided commentaries functioned; this dissertation is a study in social history that seeks to determine how presentations of what it meant to be German evolved from the 1870s to the eve of the Great War in 1914. Research topics include: * Hagenbeck's Ethnographic People Shows * The Berlin Hygiene Exhibition of 1883 * The Berlin Trade & Colonial Fair of 1896 * Karl August Lingner, mouthwash magnate, philanthropist and innovator of the textbook-style exhibit * Taking the first major international health exhibition from idea to reality * The International Hygiene Exhibition in Dresden in 1911 *** [Reprint of Dissertation with Minor Corrections and New Pagination]
